Hello All! I'm new to this forum and also very new to the boating world! I just purchased a 2001 Sea-Doo Challenger 2000 with an EFI Merc Motor! The boat is in fantastic shape! The motor has less then 300hrs on it. The compression was reading 130 across the board. Picked it up from the marina which was about 2 1/2 hrs away from my cottage. Put it in the water and it didn't get past 10 mph! What could be the problem?
