It's a Volvo Penta 5.0FL, which appears to have the Volvo SX outdrive? Looks like it just has the raw water pump on the engine from what I can see, which is new.What outdrive? Is the raw water pump in the lower half of the outdrive like a Mercruiser Alpha? Vanes from a falling apart impeller can get stuck in the cooling system if they break off.
Right!? No idea what the hell this guy was doing. Wish I had snapped a pic for your enjoyment.I would not want plain 2x4 put into my boat to repair the floor or gas tank support. Spray foam?
