Hey guys hopefully the gurus see my cry for help.
New to working on Seadoo’s but very familiar with 2 stroke and 4 stroke bikes/ atvs and cars.
I bought a seadoo speedster twin 657x with zero compression in one cylinder. After opening up the top end I saw the cylinder walls were scratched up and the piston chipped. I rebuilt the top end and broke in the engine. Once I started to bring rpms up i noticed the same cylinder was hotter to the touch then the rest. Than it started stalling out, I immediately returned to shore and saw my compression was cut in half. I opened the engine back up and the same cylinder was damaged in the same way as before. The other cylinder was fine. I’m unsure if there is a tell tale sign here that I’m missing. If anyone is interested in giving me their two cents I have pictures I could post
Thanks in advance
Kyle
