I agree with JW. I was getting a little confused with earlier posts relating to grip/holeshot. I have a Merc. Mirage ss prop. which they claim is bow lifting.
My limited experience is trim right in for hole shot and then trim out a little. As I get to about 4000rpm the bow lifts further and the boat starts to balance on the planing pad. The change is very noticable; vibration goes to almost zero and engine changes sound to a purr rather than a roar. Only testing I have done is in smooth conditions and I need more practice to get it right every time including adjusting my trim sensor so the gauge is more meaningful. I think it is going to take a few 100 dollars of petrol to learn how to drive the boat properly.
