I just pulled this engine out of a 1980 30' S2 -- it's a Volvo MD7A 13hp with transmission. It was working when I removed it. Produced plenty of power however it smokes a fair amount (grey smoke - no one has been able to tell me why) and runs warm sometimes. I have a comprehensive list of work that was done on it since I bought my boat in 2007. Recent injector work, had fuel pump tested, several seals replaced. I have videos of it running before I pulled it out.
$1200 obo. This is located in Seattle, I don't know how to ship something like this but would be willing to try.
