Bought a Razor 4 XL from Mark and have had him add cup multiple times to get the right WOT rpms but now my holeshot is average at best. I have 8 holes pvs holes in the prop and have medium plugs in 3 of the 4 front holes. When I hit the throttle it revs up to 3000 rpm and then as the boat starts to lay over it jumps up to 4500-5000 like the prop is losing bite. I've dropped the motor down lower but still have it happening. Should I move a plug or two to the back two holes or just keep messing with different sized plugs in the front (toward lower unit)?
