I have not played with the manual jack plate at all since owning the boat. My buddy used my boat a few weeks ago ans said he thinks the engine is sitting too low. I get 6200 rpms like I should most timesat WOT however I get no rooster tail what so ever, I always had my engines throw a rooster no higher than the cowling at WOT and trimmed out. This boat will not throw a tail at all and top end speed isn't all that great and it just doesn't seem to get lift. So should I try to raise it 1/4" and see what it does?
