I have a 40 hp force 1995 motor I tore apart because it has low compression on one cyl.
What i have found is one of the rings looks like it broke and got caught on the inlet port and it really chewed up the piston.
In addition.....both cylinders have a worn spot in the bottom of them the shape of the piston head like gravity took over and wore the side of the cylinders.
So the questions I have are:
1 What caused the wearing on the cylinders from the piston? and is it common to see this wear from years of use??
2 If the ring broke and I assume so because part of the ring is gone and the inlet port is chewed up a little bit and the piston is chewed up as well.
Should I rebuild or did something in the bottom end cause the wearing on the side of the cylinders and the rings to fail and a rebuild will only fail again.
3 Some say dont rebuild some say do some say get a used power head. Spending a grand or two is not an option. I am afraid to buy a used motor because who knows how long before it fails. I feel confident I can rebuild but I dont know much about outboard motors...... HELP I just want to fish...
