I looked in the SIERRA MARINE catalog and it says it's an 86 150 according to the serial number, and it should be a 2.0L. Those compression numbers and the missing airbox are dead giveaways that somebody has been monkeying with the engine. It would make a ggod engine, but definately looks as though it will need work soon. I'll keep an eye out when I'm surfin to see if I can locate you a decent 2.0L outboard or at least a 2.0L powerhead. the 2.0L engines are pretty tough, and if left stock will run a long time. I have an 81 that needs new electronics, but other than that it is a solid engine that has never been rebuilt. The hard part is finding one in a 25" shaft as most of them were 20" shafts for bass boats.
