In Memory of James “Jim” R. Blaney

It is with deep regret that we announce the passing of one of the Marine Industry’s pioneers, James “Jim” R. Blaney.

Jim was overcome by Non Hodgkin Lymphoma on February 9, 2017.

Jim, an avid sailor, joined the Mack Boring & Parts Team in 2008 as the Aqua Drive Product Manager, but Jim had been making a marked impact on the Marine Industry for many years.

It was34 years ago when Jim, the Founder, President, and passionate force behind Aquadrive Systems Inc., brought the innovative product to the US marine market. His introduction of CV joints and thrust bearings that greatly reduced noise and vibration added to the enjoyment of countless boaters lives.

Along the way he became a familiar face, a wealth of knowledge and a great celebrator of life.

Jim’s absence will be felt not only here at Mack Boring, but throughout an industry that he helped shape and advance through the last three decades.

Mack Boring & Parts will miss our dear colleague and friend and send their deepest condolences to his family and friends.

If you wish to contribute to Jim’s memory and legacy, the family has requested that memorial donations be sent in Jim’s memory to Leukemia And Lymphoma Society of NJ, 14 Commerce Drive, Suite 301, Cranford, NJ 07016


OXE Diesel – First Diesel Outboard Approved by EPA Tier 3

OXE Diesel outboard has been approved by EPA Tier 3

Cimco Marine is pleased to announce that its diesel outboard OXE has been approved by the United States Environmental Protection Agency (EPA). The OXE is the first diesel outboard engine approved by EPA Tier 3, for commercial use.

The mission of EPA is to protect human health and to safeguard the natural environment – air, water and land – upon which life depends. With the right engineering Cimco managed to develop and supply the maritime industry with an uncommonly robust, fuel-efficient and environmentally friendly outboard.

“OXE is the first EPA approved CI diesel outboard on the market. We are excited to be at the forefront of developing new technologies and leading the global outboard market to new emission levels” says Christer Flodman, R&D Technical Manager at Cimco Marine. “That’s one small step for OXE, one giant leap for outboard emissions”

“It is very important in this new market segment to have OXE receive the first EPA Tier III commercial certification for diesel outboards as production of these new motors begins,” says Tim A. Hess, President at Cascade Engine Center – OXE distributor on the U.S. west coast, in western Canada and western Mexico. “The demand for a reliable diesel alternative (outboards) to inboard diesel engines is extremely high as many customers buying gas outboards as an alternative would like longer engine life, more load capacity and greater fuel economy. The customer base for diesel outboards spans the entire commercial market from patrol craft, crew boats, water taxis, work boats, governmental and military vessels, fishing boats, etc.”

The EPA certification strengthens Cimco’s dedication to provide a sustainable and fuel-efficient diesel outboard. The OXE is a well proven diesel engine inherently more efficient than gasoline engines contributing to low fuel consumption. It consumes 42% less fuel than a comparable modern 200hp 2-stroke outboard.

Cimco Marine is the marine manufacturer behind OXE Diesel – the world’s first high performance diesel outboard engine. Setting new standards for durability, fuel-efficiency and low emissions.

Cimco Marine Delivers World’s First High Power Diesel Outboard

Hurtigruten receives 15 OXE Diesel outboards

The world’s first high power diesel outboard OXE is ready for operational use. Cimco Marine, the company behind the diesel outboard, has delivered its first engines to Norwegian Hurtigruten. It is a major milestone for Cimco after four years of thorough development, testing and validation, as well as a historical move for the maritime industry.

In 2012 Cimco Marine started to design the first generation high performance diesel outboard. The patented technology has enabled Cimco to develop, and now deliver, a robust drive unit that effectively transfers high torque from diesel engines. In March 2016 Hurtigruten accepted their first order of 15 engines through Cimco’s Norwegian distributor Link Norge AS, for use in Antarctica.

The OXE is an ideal solution for naval, military, rescue and commercial applications where safety, durability, performance and ease of service is important. Hurtigruten represents a respected trademark in the worldwide cruise market, essentially known for their trips across the Norwegian coastline described as “The World’s Most Beautiful Sea Voyage”. They offer explorer voyages in Antarctica, Greenland, Iceland, Spitsbergen and across the Transatlantic.

“We are honored to supply Hurtigruten with 15 OXE Diesel outboards. The engine’s key benefits – less flammable, easy accessible service points and more fuel-efficient – is perfectly suited for their Antarctic cruises.” says Per Wikheim, CEO at Link Norge AS. “Hurtigruten operates in various extreme environments, which makes them a perfect reference customer. With this delivery we have a fantastic journey ahead of us. It is a historical move for the future of diesel outboards. “

The delivered OXE engines will be installed on tender boats that operate with MS Midnatsoland its Antarctic cruises. One of the vessel’s first stops is the 18-day exploring voyage along the Chilean coast and Antarctica.

“Hurtigruten was specifically looking for a diesel-driven outboard, since it is less flammable and more fuel-efficient. We thoroughly compared various diesel outboard alternatives before we decided to go with the belt-driven OXE engine. We value its reliability, longer life cycle and easy accessible service points. It is crucial for us to have an outboard engine that can operate 8 hours a day and in various extreme environments.”, says Karin Strand, Field Operations and Expedition Teams Manager at MS Midnatsol, Hurtigruten. “The OXE was a relatively new product when we proceeded with our first order, but we felt comfortable with our choice. We truly believe in this product.”

With this historical delivery Cimco Marine now sets course towards full production speed. The work with implementing organizational changes and expanding its distribution network also continues.

Magnus Folin, CEO at Cimco Marine, says: “Thanks to great effort and thorough work by our staff, and support from our established distribution network, we have delivered the world’s first high power diesel outboard. We look forward to distribute the remaining engines of this pre-production, and commence full production speed according to our forecast, later this year. The fact that Hurtigruten has chosen OXE proves that it is a product that can be trusted regards to safety, durability, performance and ease of maintenance.”

Cimco Marine was founded in 2012, and is the manufacturer behind a patented outboard transmission, enabling the use of high torque diesel engines on outboard systems and in sterndrive solutions. During 2016 Cimco Marine launched the OXE Diesel – the world’s first high performance diesel outboard engine, setting new standards for durability, fuel-efficiency and low emissions.

Scania has been selected as the main supplier for Oshkosh’s H-Series Single Engine Blower US Tier 4f / EU Stage IV offering. These snow trucks will be operating globally at airports, municipalities, departments of transportation (DOT’s), and more.

The H-Series Single Engine Blower, powered with a Scania 13- liter Tier 4f engine, was recently introduced at the NEC/AAAE International Aviation Snow Symposium in late April.

“We chose Scania for several reasons. First, Scania offered us a Tier IVf emission solution that was SCR and light EGR, but no DPF. This was a critical requirement for our more northern customers such as Alaska. Second, Scania was able to provide us the SEB’s needed hp and torque requirements in a 12-13 liter platform. Third, Scania’s FEPTO (front engine power take off) ratings allowed us to drive the hydraulic pump size we needed for the SEB hydrostatic drive system. All in all, Scania was the best choice to meet several of our critical design requirements in the development of the SEB product. In addition, Scania has a world-wide service network to support their products and our customers. This was an important element in our decision process as well, since Oshkosh has world-wide distribution,” says Les Crook, Snow Products Manager, Oshkosh Airport Products.

“We are excited to expand our partnership with Oshkosh, to include supplying engines for their industry leading snow removal equipment, also within Oshkosh Airport Products. As time progresses, we expect to find a range of opportunities where both parties can grow their businesses, and the new H-Series Single Engine Blower is a great fit.” says Art Schuchert, Sales and Marketing Director, Scania U.S.A., Inc.

The H-Series Single Engine Blower meets the 2017 EPA emissions standards, allowing the vehicle to be power and energy efficient. In addition, the Scania SCR emissions solution requires no DPF.

Engine room walk-throughs save lives –

When was the last time you took a good walk-through your engine room? It wouldn’t kill you to take that walk, but if you don’t, it could kill you. It’s the heart of your vessel, after all.

So, let’s walk. First, make sure you wear your personal protective equipment because you don’t want to end up blind and deaf. Below, I’ve compiled the beginnings of a checklist that can help you keep your engine room squared away and safe.

  1. Hatches, ladders, and emergency escape scuttles: Do the hatches operate and are they tight? Do the ladders have good treads and are handrails are in place/secure? Are emergency escape scuttles are functioning and clear to open? (Don’t forget to check above them.)
  2. Lights: Do they all function? Bad things lurk in the shadows. Are battle lanterns working in case you lose power?
  3. Engines and generators: Are they clean and wiped down of oil? Are alarms and gauges in working order? Is there proper insulation and are heat shields installed to prevent hot spots? Are the pipes, connections, flanges, unions, and hoses tight and not leaking or weeping any fluid? Are the electrical connections in good shape and insulated? Are rotating machinery guards in place? Are the exhaust connections tight? Are flange shields in place? (These are fire retardant wraps wired around any place from which oils could leak. They are cheap and easy to install on pressurized flammable liquid systems, and I strongly recommend them.)
  4. Fire extinguishing gear: Are all the proper type fire bottles tested, tagged, and in place for use? Is the fixed extinguishing system tested, tagged, and ready to dump when needed?
  5. Deckplates: Are they all there and screwed down securely ? Are they clean of oil and not slippery?
  6. Hull plating, structure, and tank tops: Are they solid or cracked and leaking? Are voids labeled as confined spaces?
  7. Electrical: Are the switchboards all closed up with electrocution hazard signs affixed? Are distribution boxes tight, secure, AND labeled? Are proper fuses in place? Over-fusing causes fires. Are there any exposed electrical hazards?
  8. Wiring: Is it the right wire? Is it a rat’s nest? Is the wiring insulation in good shape, especially at any chafe points and through bulkheads?
  9. Batteries: Are they secure in their boxes with the covers in place? Are their connections clean and tight?
  10. Piping and Hoses: Are the pipes properly color coded and labeled? Are the pipe runs supported correctly? Are there any leaks—especially at joints and flanges? Is their penetration through the bulkhead secure? Piping includes fuel, lube oil, potable water, sea water, sewage, and even air. Check them all out, especially the hard ones to get at running under the deckplates and bilges. Are the hoses serviceable (not old, cracked, stiff, or leaking?)
  11. Valves: Do all valves have handwheels? Are the stems and packing in good order? Check leaks. Check the manifolds such as the bilge pumping and fueling systems manifolds. All valves should be labeled and a verified correct schematic diagram should be mounted next to the manifold, especially the fuel manifold.
  12. Ventilation: Is it working and is the ducting secure and clean? Are the on/off control switches working so you can set vent boundaries in the engine room to starve fires of combustion air?
  13. Pumps: Are they solidly mounted and labeled? Does the rotating machinery have guards in place? Are pipe and electrical connections tight?
  14. Sewage plant: Is it working properly and not illegally discharging improperly treated effluent? Is there a positive lock and chain on the overboard valve? You are required to positively secure the overboard.
  15. Grinders: Do they have their protective eye guards in place? Are they mounted securely in safe locations to work?
  16. Bilges: Are they clean and dry? Keep oil out of the bilge. Only a small amount of oil and oily water should ever be present because they feed fire and can pollute if not handled properly. There shouldn’t be any debris that could clog pumps. Do bilge alarms work?
  17. Alarms and safety placards: Is the oil pollution placard mounted and visible? Same for hearing and eye protection required labels. Is the General Alarm rotating red light functioning?
  18. Housekeeping: Is the space secured for sea? Is it clean and organized? Is there extra useless junk you can offload? Are flammables stowed away from heat sources like engines? Are there buckets of waste oil or used filters hanging around?

The items listed are not all inclusive, but it’s a start. You likely have other things to look at when you are down in the engine room, feel free to leave additional suggestions in the comments.

Sail Safe!


Great article from Tim Thomas at the ‘The Crew Report’ on the OXE Diesel Outboard!

Is the OXE Diesel outboard the future?

Tim Thomas

Swedish company Cimco Marine has developed the world’s first 200hp diesel marine outboard – named the OXE Diesel – in a move that could prove highly interesting for superyachts. Being able to fill your tender’s outboard direct from the main tanks not only simplifies the refuelling process, it also eliminates the need for carrying petrol and the associated safety equipment. It raises an obvious question – why were there no large diesel outboards on the market before now?

“The challenge,” says Jamie Clarke of Supacat, parent company to marine distributor Proteum, “has always been getting the right engine and the right packaging. A diesel engine with similar performance to a petrol version tends to be a lot more bulky and a lot harder to marinise. The clever bit with the OXE Diesel outboard has been getting the right size engine into an outboard style of delivery that can deliver the performance you need.”

The OXE Diesel includes a handful of innovations. First, it uses a belt drive system instead of gear linkages to transfer power from the engine unit to the propeller. This, in turn, means that the engine itself can be mounted at 90 degrees to that of a standard outboard, which means that a less specialist diesel engine can be used (see exploded view below). The result is an outboard unit of similar size and dimensions to a conventional two- or four-stroke petrol outboard for the same power output, the only slight drawbacks being slightly reduced performance off the line and a slightly reduced throttle response.

However, the advantages are plain to see. Not only does it negate the need for carrying petrol – and therefore complying with the concomitant safety requirements – but also running costs, available range and service intervals are all improved. Cimco cites comparative figures for fuel consumption at wide-open throttle of 43l/h for the OXE Diesel 200hp outboard against 71l/h and 73l/h respectively for equivalent 200hp four-stroke and two-stroke petrol outboards. The net result is that for the same performance and tank size the OXE Diesel four-stroke offers 70 per cent more range – perfect for exploratory trips away from the mother ship.

The advantages could also translate into operational lifecycle costs. While the unit price will be higher than the equivalent outboard (prices are still to be confirmed), the costs over the operational lifecycle are expected to be much lower. In standard commercial usage, the crossover for outlay and accumulated costs between the OXE engine and a petrol version should be around seven months. “After four years,” adds Clarke, “we think you would have spent five times more in lifecycle costs with a petrol outboard.”

With roughly equivalent dimensions – albeit with a higher weight – the OXE Diesel 200hp should also offer broadly similar performance to the petrol equivalent. “We’ve got a twin installation on a 10m Cheetah cat,” says Jeremy Paul, general manager of Proteum and distributor for the UK, Ireland and Channel Islands. “That’s a heavy boat, but we’re getting around 30 knots. Cimco have a demo boat in Sweden with a sleeker hull and a single engine that does around 45 knots.”

The outboard is suitable for a broad range of applications, and so far Proteum has registered interest from a diverse range of clients. “There’s a river taxi in Portugal that is using the engines,” says Paul, “and we’ve had a surprising number of enquiries from heavy workboats. But we’re also working on an OXE-powered Scorpion RIB for Necker Island. Basically, anywhere you’d use a 200hp outboard, the OXE Diesel is a direct replacement. It uses the same mounting as a Yamaha 200hp outboard, and the prop uses the same spline and shaft too.”

The 200hp OXE Diesel is expected to go into full production at the start of the summer, and units should be available to buy from July 2016. Further, Cimco Marine is planning to expand the range, with a variety of new units offering up to 400hp currently in development.

Yanmar’s six-cylinder 6LY3-ETP diesel engine has been selected by Silver Arrows Marine to power its distinctive, new, 14m Arrow 460 Granturismo motor yacht, which has been designed by Mercedes-Benz-Style. A pair of the 5.8 litre units, each developing 480hp, gives the pre-production craft a maximum speed of approximately 40 knots and 26 knots for cruising.

The yacht, named Mercedes, is described by Silver Arrows as “a complete re-imagining” of luxury yachts in its category. She is the product of four years’ development by Silver Arrows Marine, a UK builder of innovative luxury yachts, in collaboration with Mercedes-Benz. Yanmar is a technical partner in the project.

The design of the yacht, with its long foredeck above a planing hull with a narrowly tapered freeboard, arched roofline and gently dipping rear, deliberately evokes the feel of today’s Mercedes cars. Beyond looks, an important part of the “sensual purity” of the design concept is smoothness and efficiency in operation. This is one reason why Silver Arrows Marine chose Yanmar’s refined and efficient engines to power the project.

Silver Arrows Yanmar   Yanmar powers Mercedes styled motor yacht

“We know that Yanmar is a reliable company, with a philosophy that matches our thinking,” says Silver Arrows Marine CEO Jacopo Spadolini. “The Kaizen philosophy (of continual improvement) drives the strategies of both companies,” he states.

The spokesperson continues: “Another very important aspect is that the after-sales and assistance provided by the brand can be found all around the marine world. The Yanmar service points are extremely efficient, with very skilled engineers.”

The choice of Yanmar was reinforced by the fact that its marine engines are all purpose-designed for marine applications. For Silver Arrows Marine that ruled out competing marine engine brands whose product offering is largely automotive-derived.

After its launch on France’s Côte d’Azure in April, « Mercedes » is expected to be commissioned in June ahead of going into full production later this year. Looking ahead: “Building on our relationship with Yanmar, Silver Arrows Marine plans to create a new collaboration for engines that will be launched in the future ,” the boat company reveals.

Aquadrive CV Axles improve 34 ft. Navy boat

The new U.S. Navy 34 ft. high-speed patrol boats now utilize Aquadrive CV – constant velocity axles. The first few boats installed truck type U joint driveshafts. The U joints restricted the engine placement and contributed to the vibration and noise. Aquadrive CV joints eliminated the precise alignment demands required by universal joints and reduced the vibration and noise. Machinery placement, vessel performance, and stability were also improved. In 2007, the CV axles were tested, approved and installed on more than twenty of the new U.S. Navy 34 ft. water jet boats and are now standard equipment. SeaArk Marine designed and will build 29 additional boats, beginning in August of 2008. These 34 ft. patrol boats are used by the U.S. Navy Seals and are deployed worldwide.

After 33,000 hours, Isuzu engine gets new life with Mack Boring rebuild

Rhode Island lobsterman Bill Long learned long ago that if he is good to his Isuzu E120 diesel, the engine will return the favor. After 23 years and 33,000 hours of service, rather than retire his “old friend”, Long chose to send the engine to Mack Boring to be rebuilt. The Isuzu stood up to the rigors of commercial fishing, including the continual start and stop demands of tending 300 to 400 traps per day, up to 40 miles offshore. The engine also powered the hydraulic system, running a hauler, winches and net drum. In return for routine maintenance, and a habit of keeping engine rpm’s in the 1800 range, the engine gave Long what Isuzu diesels are famous for — extended, profitable and dependable service life. Rebuilt by Mack Boring, the Isuzu is now ready to do it all again. Continue reading “After 33,000 hours, Isuzu engine gets new life with Mack Boring rebuild”

Diesel Engine Seminar Preps Sailor For 10 Years Of “What-Ifs”

Devin Taylor Boat Union, NJ… It’s routine for ocean voyagers to familiarize themselves with diesel engine maintenance. With a 10 year circumnavigation just months ahead of him, though, 52 year old Devin Taylor was not content with just understanding how to change fluids and filters, replace a belt or service an impeller.

For Devin Taylor, a lifelong dream was soon to become a reality. Having just retired as an industrial engineer, the time in his life is right to make his lifelong dream a reality. Together with his wife Liz, the Taylors had thought about the voyage over the years with increasing seriousness. Their association with fellow sailors at the Island Packet Owners Association, the Seven Seas Cruising Association, the American Sailing Association and the US Power Squadron, built their confidence and helped them understand the prudent preparation steps. Devin and Liz each committed to building their skills in disciplines that would help them in their travels. They acquired advanced pilot training, celestial navigation, weather and ham radio skills. Liz would learn Spanish and become proficient in first aid. For Devin, the learning was to include French and an understanding of their diesel engine.
