When it runs in a tank it seems to have plenty of power but under load it feels like your towing another boat. It would be perfect if you did nothing but trolling but when you crank up the rpms it struggles to push my 14' aluminum boat.
Compression is 60 lbs. in each cylinder. Obviously 80-110 would be better but I've read that as long as they are similar, even lower compression is okay in these old timers.
Is it possible that an engine can just be tired? Would a ring job even make any difference? What should I look for if I do a spark/gap test and could a weak spark be the cause of low power?
