Hey guys I am not sure what to do but I would like to know if someone has any advice. I have a new SBT motor with maybe 10 hours on it. New it was only getting ~120psi in each hole. When I called SBT a few weeks ago the tech that I spoke with informed me that 120-140 PSI was within the tolerance of a new motor and they would not replace a working motor with 120psi in each hole. The engine is under warranty until next January. Just today I measured the compression again and now is reading ~110-115 per hole. I know the gauge is working fine because I also measured my Seadoo 787 engine at 145-140 PSI. What should I do? Is this something I could fix by replacing the piston rings? Would that void the warranty? Or would it be advised to rebuild the top end?

Thanks

Please do not take the engine apart that will void the warranty. Give the warranty department a call and they will help you out. 1.877.330.0231.
Thanks

Cool thank you they said my compression was too low and went ahead and gave me a tag # for return. Bad news is I have to pull apart the motor (again uugh) and ship it back.
