Hey guys, I bought a aquacraft supervee nitro 27 (love the boat ) took it out and ran 4 tanks of 30% nitro through it, still needs to be leaned a little more . runs realy good but at about 3/4 throttel it starts skipping or porpoising, not realy bad but is this nomal? it just runs so much smoother at 3/4 and lower. I'm running fully stock out of the box. on glass like fresh water.I know there are a lot of adjustments but which would you suggest ?
Thanks John

If there are trim tabs on the stern of the boat, tip or bend them down slightly and test the boat.
Continue to tip these down till the boat runs smoothly at speed.

If there are no trim tabs, move or add weight toward the front of the boat till the the boat runs smoothly at speed.

I agree with Umi, but in reverse of the way she described it. I would rebalance the boat first and then try the trim tabs. I would also check the thrust angle to see if the prop is pushing slightly up, down or straight back. If the prop is slightly up, it will lift the nose and can cause the boat to "porpoise" as you described

Thanks for the info it does have trim tabs but i"m not shure if its that or prop angle guess this weekend I'll just have to try them and see whitch one helps I just dont want to adjust the wrong one and cause drag
