I am running three blade Cleaver props! Like I said the boat get up on top when you are in rough water but when you are in smooth water the boat will not lift. For what I here is that I should be running four blade props with what I have & by doing this it should lift much better.

2002 31 AO with 2002 300X motors
I have seen 84 with 15 1/2 X26 4blade hydromotives QIV when I replaced the 15X28 cleavers.
Then I ran 15 1/4 X 28 bravoI 4 blades and got 87 with 4 people 90 by myself.

All the props had a porpoise at certain speeds, which is normal for a tunnel hull. The cleavers were the worst. .If I ran through the porpoise with the propshaft level with the bottom of the boat, then lifted and trimmed the engines it worked best. Do you have lift as well as trim or are your engines mounted at a certain height?
