Crazy OM617 marine power idea
Howdy all, been a while.
I want to pass this idea by y'all and see what you have to say. I recently acquired a 21' Donzi cuddy cabin with a V6 (not fast) gas engine which needs to be replaced. How crazy is it to consider the possibility of swapping in an OM617? My biggest concern is weight, secondly: power. I would run a fresh water cooling system. Has anyone by some chance heard of someone doing this? How much does a turbo OM617 weigh, and what does it "redline" at, and what are the power specs? BTW, my 190D is running great, I put over 25,000 miles on it with nearly no troubles. I am very happy with my 5-speed swap. Thanks, John

There are at least a couple of threads on here about marinized MB diesels. At least one company did it a lot. I think mostly they were 616's or other MB diesels. Not a crazy idea.

Seems like a good idea, Its done in Europe allot more. A 616 might work well also, cheaper to overhaul and plenty of power for a 21" boat?

Make sure to use a turbo engine

4 cyl version of the 5 cylinder 617. Made by MB between 75(?) and late 80's. (Last used in a car in 85 I think) Found in 115 and 123 bodies cars as the 240d and almost all the vans with '7' as the last digit before the 'd' in the model name. Still made in India by Force Motors. Never turbocharged by MB. Turbocharged by Force.

Not crazy at all, just expensive and time consuming. You would have to find all the marinized parts or do some serious engineering yourself. Cheapest bang for the buck if you want a diesel in your boat is to find a used Yanmar setup with the outdrive to go with it. RT

I have seen them fabricated for American V8s that basically were stainless tubing for the exhaust runners that had a larger stainless canister TIGed around the runners. Any heads up fabricator that can TIG stainless could make one. Maybe you could get away without the special exhaust manifold if you wrap the existing one in kevlar tape to insulate it and have a separate pump be it electric or engine powered to flow water through the fresh water cooling system. Also, since diesel is not volatile like gasoline, you shouldn't have to worry about a marine starter or alternator. I think it has to be super hot for diesel fumes in the open atmosphere to ignite from a spark. I would still put a blower in the engine box to blow out any fumes before I started it the first time of the day. Is your goal to have a diesel powered fleet of cars and boats?

This has been talked about a couple of times before...and I continue to believe that the biggest problem in using a turbo 617 would be the absence of a governor at engine speeds abpve 1100 RPM.
Here's links to prior marinazation discussions: MBZ Marinization Parts 300 turbo diesel in a boat Diesel Engine for Marine Use Check out this OM 617 Marine conversion project! Enjoy!

If that exhaust plan would work, mating the engine to bellhousing and connecting starter + gimble housing would be the main stumbling block. Any other ideas would be great. Quote:
BTW, what is this talk about no governor? Thanks, John

Known fact that 617.92X engines aren't governed above apprx 1100 RPM.
Look at those other threads referenced in post #11.

What if you get into a car with a 617 engine and revv it in "N"? Does it instantly redline, or bounces all over the place?
