Beta Marine Diesel Engines

Beta Marine Inc , based in England , has been marinizing small marine diesel engine Kubota [Japanese] industrial diesel marine engines. These small marine diesel engine kubota marine engines have an excellent reputation for high horsepower to weight ratio, longevity, smooth running, and low emissions. They are the most technologically advanced small marine diesel engines available today for marine applications. The available engine range is 10 through 75 horsepower. All Beta Marine engines are fresh-water cooled, naturally aspirated [non-turbocharged]. Several makes and types of transmissions, with assorted reduction ratios, are also available to suit most any vessel.

Several Beta small Marine diesel engines are available to replace the Atomic 4 gasoline engine depending upon the vessel's displacement. General guidelines for displacement hulls follow, but please contact Joe DeMers for a specific recommendation concerning your boat and application.
  • Boats displacing up to 7,500 pounds may use the Beta Ten engine.
  • Boats up to 10,000 pounds may use the Beta Marine 13.5 hp engine.
  • Boats between 10,000 and 14,000 pounds need the 20 hp Beta Marine engine.
  • Boats between 14,000 and 18,000 pounds require the 28 hp Beta Marine engine.
The above replacement engines are available with Atomic 4 engine mount spacing at no additional cost. This precludes the need to modify the engine bed or stringers to accomodate the new diesel engine. Obviously, this saves much time and expense. Beta Marine has the only Atomic 4 replacement engine line with this terrific feature.

Low maintenance and repair cost is another advantage of Beta Marine diesels, as engine parts are available worldwide at anysmall marine diesel engine kubota farm tractor dealer. Check your yellow pages for a nearby dealer. You will pay "tractor" prices, not "Marine" parts prices. The savings can be considerable, especially when compared to Beta Marine's competition! Also, Beta Marine is happy to supply anyone with part numbers for routine maintenance parts, so you can shop locally for your best deal on Wix, Napa, orsmall marine diesel engine kubota lube oil filters, fuel filters, V belts, air filter, zincs, Jabsco impellers, etc.

Beta Marine recognized the oil change problem years ago, and supplies all their engines [optional on the Beta Ten engine] with a manual oil change pump mounted on the engine and plumbed to the low point of the oil pan. To perform an oil change, just open the valve at the base of the pump, remove a small cap at the pump discharge, and operate the pump with one hand. Unlike the cheap hand pumps we are all familiar with [and disdain] the Beta Marine pump is all brass, high quality, works easily and very efficiently. I install a piece of clear hose over the discharge pipe and lead it to a sludge bucket.

To finish the oil change, just close the valve, replace the cap, change the filter, and add new oil to the engine. This setup actually makes oil changes fun!

Sound Marine Diesel, LLC is now a Wolverine engine heater dealer. Wolverine engine heaters provide the following benefits:
  1. Improve crankability, particularily during cold weather. This means less wear and tear on the engine starter and batteries, and quicker engine starts.
  2. Reduce cold start wear, by ensuring oil easily and quickly flows to the engine bearings during startup. Oil pressure builds rapidly, since there is minimal flow resistance. This feature alone, will save you money and expensive engine repairs.
  3. Reduce acid and water accumulation, by keeping the oil warm.
  4. Reduce white exhaust smoke at startup, by helping to maintain engine compression, which leads to more complete fuel combustion, and reduced blow-by.
  5. Helps to get the engine to operating temperature faster, since the oil is already warmed, and thereby reducing engine wear.
The bottom line - Wolverine heaters will prolong the life of your expensive engine, while maintaining engine performance and greatly reducing wear. They are cheap insurance, that saves you money!

Wolverine heaters are 120 volt AC powered, [240 volt powered are also available] and cost little to operate. After installation, just plug into shore power, and the heater immediatly starts to warm the engine. Think of it as placing your engine on a stove. As heat rises, the entire engine becomes warm, leading to the above benefits.

All Wolverine heaters have the heating element embedded in a pliable silicone pad, that's .075 inch thick.

Unlike conventional engine block heaters, Wolverine heaters attach externally to the engine oil pan, without any need to drain coolant from the engine or remove a freeze plug.

Installation is straightforward. Just clean the engine oil pan bottom of any accumulated oil, sand to clean metal, and apply the self stick heating pad. Now plug in to shore power to keep your engine warm; ready for a quick startup. There is no maintenance required.

Wolverine heaters are available in 5 models, to fit a wide variety of engines, as determined by the oil pan capacity.

  • Model 4.5 fits 1 to 3 quart capacity oil pans, 50 watt output, uses 1/2 amp of current.
    Dimensions - 1.25"x 3.5"
