motor locked/now free
This is a 1986 40HO yamaha model is 40ETLK.
I picked up this boat from son in ga and it started and run for about 5 min. shut off would not restart.
Came home with it and motor was sized up.
I removed plugs, used some wd40 and sometime later was able to unlock the motor with wrench by turning clock wise and counter c/w.
I then thought i should check the cyl since compression was low 85 to 105. water passage bottom cyl real bad. look at all cly seen worse a little scaring and it appears one cyl is dragging when turn by hand.
Q How is the best way to free up then engine with doing a complete tear down and o haul.
