I am surprised no one has mentioned these engines yet. I have seen the 55hp Multi-Fuel-Engine (MFE) before but these 30hp MFE's are new. I would love a couple of these. Robust and rugged. http://www.youtube.com/watch?v=Xp2ueXpcGQk |

According to the notes on the video, the MFE engines are only available to the Department of Defense. Perhaps that explains why there has not been much prior discussion about them. |

I suspect they will not meet emissions standards. If they they are running JP5, or diesel, they must be putting a ton of fuel in the cylinders with a lot of oil. |

Great comment. I had never thought about that aspect. |

http://www.evinrude.com/en-US/engines/multi_fuel_engines I find it interesting that they include them on their public web site yet the public can not buy them. |

I just looked up the 55 online and it said they are available to the public. A few years ago I saw them listed on Eds Superstore and I think they were in the $15000- $20000 range. They can be submerged,dropped from a helecopter and floated up from a submerged submarine. The government wanted something which would run on something other than gasoline. The ad said navy ships were forbidden to carry gasoline. The engine is manual start and can be had with jet pump or regular prop lower unit. |

Evinrude/Johnson has made great smaller engines for the military with dewatering capability for over 20 years. You can find their 2 stroke 55hp and 35hp MARS engines on surplus websites. I am actually surprised they moved away from those engines given their simplicity. |

As far as diesel is concerned, diesel is an oil. JP5, if I remember correctly, is very closely related to kerosene. Why would these fuels require more oiling than does unleaded gasoline. The Department of Defense (DOD) generally procures power equipment which meets federal emission requirements. To a very great extent DOD buys off the shelf equipment except for tactical equipment such as tanks, helicopters, tactical vehicles, etc. Butch |

The MFE outboard is direct fuel injected so the oiling system should be quite different than a conventional 2-stroke and quite similar to the DFI targeted oiling systems. |

From what I have read online, the Mercury JP Optimax and Evinrude MFE are primarily designed to run on jet fuel but the MFE can run on a mix with diesel for a short period of time. My logic for the extra oil is the lack of lubrication that JP5 has compared to regular gasoline. I theorize that it must either have oil mixed with the fuel or extra oil injected. DFI engine while primarily designed to have pin point oil injection can run without issue with TCW3 oil in the fuel. |

This is one of the better descriptions of the MFE outboards: Evinrude E-TEC Multi Fuel Outboard An Evinrude ETEC Multi Fuel Outboard Will Burn Just About Anything You Can Pour Down Its Throat - Evinrude's E55MRL multi fuel outboard motor Evinrude's multi fuel outboards are giving us a tantalizing glimpse into the future. The Wisconsin-based company builds direct injected two-strokes with EFI mapping programmed to burn diesel, jet fuel ( JP-4, JP-5, JP-8 Jet-A and Jet-B), kerosene, or bio diesel as well as common gasoline. Fuel selection is no more complicated the flip of the switch. Multi Fuel Engine (MFE) technology allows the U.S. military to transport outboards via aircraft or ships without having to deal with volatile gasoline fumes. That's important because gasoline is forbidden aboard U.S. Navy ships (the US Department of Defense Common Fuels Initiative). While the MFEs are not designated as Evinrude E-TEC engines, E-TEC technology is incorporated throughout, including E-TEC injectors, the fuel system and an onboard computer. Other innovations include special cylinder sleeve oiling, modified deflector pins and mapping strategies. Note the combustion chamber has been significantly re-contoured in order to burn a multitude of carbon-based fuels. Affectionately known among the engineering staff as the Vindicator, the Evinrude 55 MFE is available with either a conventional propeller or an impeller-equipped jet pump. Built to U.S. military specifications, the pump jet is a large impeller unit attached to a full gear case that provides superior thrust and performance when compared to conventional jet pumps. Painted matte tactical black, the two-cylinder 55-horsepower MFE is rope started with a conventional break-down tiller steering arm.
Beyond multi-fuel flexibility what really gives E-TEC value in a tactical, or third world, setting is the zero break-in time. Right out of the box they can be started and run at full throttle without babying. And because they are extreme low maintenance their survival rate is greatly enhanced, a trait that's especially important in high stress environments. Evinrude 55 MFE engines fitted with the jet pump power the United States Marine Corp's fleet of FC-470 Zodiac boats and Combat Rubber Raiding Craft (CRRC) used during small craft operations. They are also available to civilians. |

I suspect the "flip of the switch" for different fuels allows the engine to adjust injector pulse width and oil amounts for the different fuels. |

Robert, As the engine can be run on straight diesel or virtually any jet fuel without adding oil to the fuel tank I suspect the flick of a switch is to switch from gasoline operation to multifuel operation. I learned in Haiti in 1994 that a then current era diesel Chevrolet Blazer would run quite well on jet fuel. It was not necessary to add oil to the fuel tank for the engine to run well. This was before the era of ultra low sulfur diesel fuel so I expect current generation diesels designed for current fuel will also do well operating on jet fuel without additional oiling. Thanks for initiating this interesting thread. Butch |

Interesting my links are to the current web site. Evinrude needs to update their website. I found a 55hp for sale by a dealer starting at $20,450
