I've just noticed that on the Evinrude website there is a section "Govt & Military" and in it there is a section on Evinrude multifuel outboards, including a 200hp E-TEC. Here's the URL: http://gov.evinrude.com/communicatio..._MFE_Final.pdf
They'll run on JP-4, JP-5, JP-8, diesel, F-76, DF-1, DF-2, kerosene, or gasoline, and can change fuel capability "at the flick of a switch.
In New Zealand (where I live) gasoline is heavily taxed . In contrast, diesel is not so heavily taxed, and diesel road vehicles pay a road user charge based on distance travelled and the unladen weight of the vehicle. Consequently, for powerboats gasoline costs almost 40% more than diesel, so a 200hp E-TEC that runs on diesel would be a winner as long as it cost about the same as the gasoline version.
Do any of you have any knowledge of these motors that you could share with us?
Thanks in anticipation.

It says, "from gasoline to another fuel, just flip a switch". How can they do that?
Apparently with a "Flip of a Switch", we ordered two of these for a project we are doing for KBR, they are the smaller motors not the 200, so when they come in I will have to do some reading up and a possible test ride one of them....I will start a new thread when I have the results of my "Backyard Laboratory Tests"

i read this info on another site (e-tecinfo.net, i think). im no engine guy, and i sure dont know fuels, but i guess one of the "JP"s is close to gasoline, and the 'flip of a switch' thing might be true. i sure cant see going from diesel to gas that way. you would have to change injectors and, what, fuel pump? and what ever else.
for the original poster, that e-tec info site may give you some leads as to the availability of the diesel e-tec.
The Flip of a switch changes the engine calibration in the EMM (which accounts for fuel characteristics). The injecotrs and fuel pump do not neet to be changed. It truly is the flip of a switch.
Wasnt there a diesel outboard some time in the past????? Seems like Ive seen either a photo or a thread concerning it. Seems like it would be awfully heavy for its displacement, dont diesels NEED a cast iron block to handle the compression levels?????

There are diesel outboards in service in the world (in fact, I think there are more than many people realize). Most are small hp models used on sailboats as best as I understand
I would imagine that Evinrude is igniting diesel fuel with the spark plugs in the ETECs instead of via compression as in conventional diesel engines. My simple caveman brain can understand no other way.
A couple of manufacturers have done this. THese engines are not diesel cycle but standard 2 stroke that just burns diesel. I understand they aren't very effecient and only done so that the military doesn't have to carry volatile gas.

My understanding is that its still a spark ignition engine, just running diesel fuel instead of gasoline. I would think it would not need to inject as much diesel fuel as gasoline to make the same HP.
Help me out on this, I must be missing something. What good is this "flip of a switch" for the recreational market? Why would I want to carry 2 fuels on board? Am I supposed to add a tank?
It sure does sound "neat", but I fail to see a practical recreational application.

It is not for a recreational application. In fact you can't even buy it for recreational use. It is for the military. If you visit the page you will see only those with government accounts can place orders. The reason these were developed is that the military want to carry a less volatile fuel on board. Furthermore they are attempting to make everything they have run on a single fuel JP-5.

Bingo. I've heard the same. All Navy vessels to run on diesel fuel by 2008 or so. I've heard the navy uses a less volitile fuel (JP5) in their turbines than the Air Force, because the AF has the luxury of putting their fuel (JP4) in a relatively safe, far away place. The Navy has to keep their fuel on the boat somewhere - not so safe, not so far away.
