Hello everyone, recently I was having issues keeping my boat running at idle when dropped in the water. I was adviced to replace head gaskets as original compression test was 100, 70, and 50. I have a 2 stroke single carb force 70hp. It runs and sounds fine on the hose and it went for a decent run on the water until we stopped and idled and then wouldnt start back up. I replaced my head gasket, upon replacement i noticed leaking into cylinder 2 and cylinder 1 has low compression. Cylinder 2 has a little damage on the piston. After replacing the head gasket my compression test improved to 90, 90, and still a 50psi on cylinder 1. Do you think the picture displayed for the damage in piston 2 is causing the low comp in cylinder 1? I will take her on the water tomorrow to test and see if she can hold a whole days worth of boating. Atleast compression improved.
Would you recommend doing an engine rebuild if you think the piston 2 is the cause? Thoughts? Ideas? Thank you so much in advance
