I bought an engine like this 16 years ago for my 1924 catboat. The previous owner of the engine had noticed a loss of power and a Volvo mechanic had recommended a new engine. That's why I got this for very little money. When I got home I discovered, that only the actuation lever for the gouvernor was worn out, so that it was no longer possible to apply full throttle. A little bit of welding and filework fixed ist.
Hi Boatmattias, interesting comment. The engine came bolted down in its crate. I added the fuel system and made a starter box so I could test run in situ. Under the green paint (seen in the video) was a base coat of "duck egg blue" colour. You could be correct with an engineering school theory.
Hi Nick, I got the engine from eBay. Try and buy a runner, even if it's got starting issues or low compression. A top end rebuild should sort out the problems and give you a reliable engine. Hope this helps?
