$500 seems a bit much for the non runner (IMO) being it is from a boat (in our area) it is highly likely these were salt water cooled engines. They have heat exchangers and water jacketed exhaust manifolds on them, so there would be some modifying right there.

Plus you never know if these came from a salvaged (sunk) boat.

If I were to look into these I would ask him if they were salt or fresh water cooled engines.

My first big boat was a 42' Luhrs Sport Fisher with twin Chrysler 318"s. It was also salt water cooled. It is amazing how the engine manifolds and heat exchangers can look like new on the outside but actually be paper thin on the inside form years of salt water as cooling.

And you brought up a great point! After the hurricane we have to be even more careful buying things.

I believe we've had 4 major storms in the last year and a half. There is a lot of cars and trucks that went under too. It is funny that thinking about that Cummings reminded me that I have a small 4 cylinder FORD diesel generator in my basement(buried behind 2 other big generators). I'll have to try and dig it out.

The folks above have brought up some good points to check into. Tapered crankshaft and cooling jackets. Also if you have to start replacing the fuel system components your investment is going to go up in a hurry. In my opinion I would leave these and look for a running diesel that wasn't marine orientated. Not being in a hurry and asking lots of questions can save you hundreds of dollars.

Plus being from a generator it is probably a governed fixed engine speed. Sent from my SPH-L710 using Tapatalk 2
Can you change a fixed speed engine to a variable speed engine? I have a deal working on a couple out of reefer cooler units. Is it a matter of hooking up a throttle cable or is it internal?

The ones I've done only required backing out the stop screws on the throttle arm and installing a throttle cable to the dash. Some may require changing the governor springs and that could be internal.
