saw an add for a 55 or 60 hp outboard that would run on damn near any fuel u put i it, i think envinrude made it. it sas orifginally made for the seals to use. they could sink it while attached to a zodiac, refloat it fire it up and go.. any of you guys ever been in a boat with one of these engines on it? thx

no but that sounds cool i have seen them on youtube where did you see the add

its been a while it was a two page add in a magazine i cant reemember which, i was wondering if they ran low rpm like a diesel

I have spent a many hours on a boat with a Diesel Outboard....... What would you like to know?

in a word... everything lol,

what make was it? how many hp, what kind of rpms did it turn, what did it weigh compared to the same hp gasoline outboard, was it easy to start? was it electric start? any major drawbacks? thx so much for any info, rm

Yanmar used to make a small (27hp i think) outboard, and there is a Company out of Sweden that just came out with a 200HP one OXE Diesel is the name of the company. Don't know of any others or have any experience with either.

Matritime_Eng what outboard diesel did you use?

It is my own design, I had thoughts of bringing it to production but it was too costly for a private company to invest in tooling, building, ect, so we decided to close the company. The specs are as follows: 230hp, 4000 RPM, around 850lbs. (Could be 300hp and 4500 RPM with a computer change)
