    489 Motor Build - Piston and Cam combo for 20' Aristocrat Jet Long story short, the motor that was in the jet boat was toast. Low compression on 3 different cylinders, 2 of which had 95% leak when tested with a leakdown tester. Needless to say, the motor is now out of the boat and at a machine...
