This engine is completely rebuilt by Island Diesel in Nanaimo. It just needs a good boat hull to install it into. It can be used for any type of project or idea if you need 190 HP to work for your project. New pistons and connecting rods, crankshaft, lifters, rings, etc. Needs to have the head installed and paint to be ready to install. Call me for more info. My asking price (3500) is half of my cost as the head cost me $1100.00 and the block cost me $5000.00. It is best suited for the Mercruiser Alpha 1 gen 1 outdrive. I have a lot of Mercruiser 3.7 parts for sale if anyone is looking for a part?
