I just purchased a 1995 sea-doo spi with the white rotax 580. Did a compression test with 115psi on both cylinders? This seems a bit low to me but most people say not to pay attention to the amount of compression but focus on the difference between the cylinders. The seadoo also seems to cavitate a lot so I looked at the impeller and it needs to be changed. Any Suggestions?

115 psi per cylinder does seem a bit low. I would check out the rideplate and make sure you have a good tight seal.
