I have a 94 PII bass cat that I just put a 98 Yamaha 200 hp 0x 066 Vmax. I set the boat up at 3.5" PTP running a 25P solas 4 blade right now. Hole shot was pretty descent at 3100 on break over. top speed was 62.7 at 5300 rpm. I have bought a new tach as I think that mine is not reading right. need some help figuring out what I need to do to make it run right.
