Hey everyone, I've been an OMC man all my life but money is limited now and old OMC engines are expensive. I have an old 70's center console I'm looking for an engine for. I found what appears to be a 70's model 3 cylinder Chrysler with controls still on a boat for $300. I'd scrap the boat but this seems like a good price for an engine with controls. I know there are hardcore Chrysler fans out here, who are the people I want to hear from! What do i need to know about these engines other than compression and make sure to clean the carb as well as all the other basics. Heres the picture off of craigslist of the engine.Chrysler.jpg

Not much to know. The engine is an older 2 piece lower unit which would make it before 1979. Depending upon distributor type, it will either have points (earlier) or an electric eye. If it has the electric eye, the distributor will say electronic.

Change the lower unit oil, change the fuel pump diaphragm and gasket, and change the water pump impeller. Put a fuel filter between the pump and carbs. Use 50-1 TCW-3 oil mix and she may very well run until you die.

18 spline thrust pin props are becoming a bit scarce but can still be found. You may need to contact franzmarine@aol.com for the impeller--it is not sold on iboats.

The 2 piece lower unit is a bit slower than the later one piece bit they can not be swapped. If at some point you do want to convert, you put the block on a one piece midleg. Pistons and rods never changed and neither did most of the internals so parts for the engine, including carbs can still be swapped in from Force engines.

300 is about the correct price for that engine--unfortunately, while they do run well, no one wants them. You will find that equivalent OMC or Mercs will outrun you. Fact of life--The engine was designed as old school entry level and simply does not have the goodies to run really fast. It can be modified though.

I can not tell from the photo, but if it does not have power tilt/trim it can be retro-fit with a TNT from almost any three or four cylinder Chrysler or Force up to about early 90s.

Frank has said almost everything. Looking at the hood and it is a 75Hp, it is from 1974 to 1977. In 1978 the hood had other decals.
I think this 3 cyl. old Chryslers are lovely, not as fast as the 800 Merc from same time (I have one and I also have some Chrysler and Force engines too) but the Chrysler is much easier to work on.
If you maintain it well and not run hell out of it, leave the air/fuelmix screws at about 1 1/8 turn out from lightly seated and as Frank says put a fuel filter between the pump and the carbs. These engines will run forever.

Had two of these 75hp motors, one a 76 model looked like yours and one an 80 model, both great engines and only reason I got rid of them was I bought a 100hp Chrysler.

I didn't say there would be no frustration, but they are a good engine to work on.

Haha!! I hear ya! OMC's can be frustrating at times as well! An off the wall question, I know many older outboards the tilt and trim unit bolted to the transom bracket or something like it. Could this engine I'm looking at be retrofitted easily with t&t if I had a donor motor?
