OK here is the deal. I am in the process of tearing down and going through my 97 720 motor off of a Sea-Doo GTS Jetski. I replaced all four outer bearings on the crankshaft along with the other seals, I want to know if I assemble the motor without putting the pistons in can I pressure test the crank case to see if the outer seals are leaking at all?
