Great to hear it's back up and running, but now to figure out why rpms are only at 7000. Get it up to around 8000 where it should be and that boat will probably gain another 10mph.
Just had a new super charger put in my boat. You are missing a gear. I did drive mine for a few times last year but it ran slower. Had to replace oil pump and they dropped the crank. Luckily no top end damage. But that gear reaked havoc on the oil pump and SC. Cost me 3700.
