Can i use a volvo penta outdrive on a mercruiser engine?

I have a 1972 Starcraft with a 140 mercruiser and a pre alpha outdrive. Can i use a volvo penta outdrive on a mercruiser engine.||| After reading the answers so far, I can understand your confusion. In your exact case, my answer is don't. There are just to many problems, from the differences in the engines, and transom shield, to electrical. tilt and trim etc. Just to much. I love Volvo but I've also worked on OMC and Mercruser. It's easier to repair that you have. Good luck!|||Yes you can but you will need the Volvo Penta SX Outdrive as it has the same basic transom cut out as the Mercruiser. Since both use the chevy 151 cubic inch 4 cylinder the base engines are totally interchangeable





Take off the exhaust manifold bell housing and engine coupler what you have left is all you can usead far as the engine goes. Everything else that is painted Merc black will need to be replaced including what is left bolted to the Transom, with Volvo Penta SX components and including the engine mounted Raw water pump





It would be far cheaper to replace your old unit with one that is a direct bolt on.|||Sounds like you need the following:





Masters in Automotive or Marine Engineering





Production specs of both outdrive systems





Precision manufacturing CAD system.





Multi-million dollar manufacturing facility





Millions of dollars in development, production, and salary expenses.








So unless you have all of this and a few items I might have not mentioned, the answer is a big NO.


|||There is a company that makes an aftermarket replacement out-drives for Mercruiser. They advertise in all the boating magazines. I cannot remember their name now. Anyone know?|||Nope- You can not use your mercruiser engine on a volvo sterndrive. Volvo stern drives have no raw water pump built into them. Merc has a big pump on the input shaft to the lower unit.|||If you can figure out how to adapt a Volvo engine coupler to a Merc flywheel, sure. Is this some kind of science project?|||No. Find a new drive. They are out there.
