Hello all, I just purchased a 60 degree 1992 Evinrude 150 from a dishonest seller and discovered it had a cylinder with 0 psi compression. The other 5 cylinders were reasonable at 85-95 psi. After pulling the head I found what looks like aluminum chunks coating the cylinder wall. Also looks like it’s from the piston as it had chips in it? Seller had said it started smoking but still had good compression (right lol). Im very experienced working on Evinrudes and have the manual but have never repaired a cylinder/piston. Can I just chemically remove the aluminum? Also I’m assuming this piston is toast? Are they just surface chips on top? What are my options aside from full rebuild? What would cause pistons to chip?
Says my pics won’t upload but I’ll keep trying. Thank you for the help!!
