Well the troubles continue with this motor. It is a 1989 #856X9H. Although the powerhead is stamped 1991.(See pic) I posted a while ago about a compression issue I was having and turns out the Head gasket was bad. Replaced. I ran great after that. Good compression in all Cylinders. Until....... About a month ago. Was having issues with it starting. Started out with the basics pretty much. Fuel, Spark, Compression. Umm Why is cylinder 2 compression only 30psi? Maybe blew another head gasket? Nope. The first photo is The top of Cylinder #2. You can see there is a indent in the piston right at the cylinder wall(almost looks like someone took a screwdriver and pryed on it). Well damn!! My only guess is that the piston ring broke off and got caught one of the ports and the piston caught it on its upstroke. That is a wild guess. Have any of you seen this before? I really don't want to have anymore issues with this motor. I'm thinking of just pulling the powerhead off and putting in new piston and rings in all three cylinders. Or should I? The compression on all three Cylinders is 1-93psi 2-30psi 3- 90psi. Or should I just replace the 2 cylinder piston and not pull the powerhead? But my only concern is that if the ring did break, where did the piece go?? Again that's just a guess as I haven't taken the piston out yet. If I do a rebuild, expect me to be on here a lot. I have rebuilt engines before, but never an outboard. So it will be a bit of a learning experience for me. Thanks again!!
