Have some ideas is the sterndrive a Bravo or an alpha Im guessing on that a Bravo 1 or 2. What is the age roughly pre 96 Bravo drives had trim in limit blocks on the transom side anchor pin. These could be turned 2 ways to maximise or minimise drive tuck in. Also on the later drives on the outer anchor pin the elongated the hole the pin goes through and put in a spacer. This to if you put it in which ever way will minimise or increase drive tuck in giving you full trim in when opening the throttle which may help in getting you on the plane quicker

I had the same problem but on a very different boat - a 36 footer which couldn't get its stern up so was always pushing uphill.
In short - yes, bigger trim tabs did help me. With small tabs, to generate any real lift you have to set them down so far that they act as brakes. Self defeating. I went to Lancing Marine (great firm by the way) at Brighton & replaced my tabs with bigger ones. I also bought two extra tabs & fitted them as fixed tabs so that the whole stern area is in effect tabbed.
The extra lift is very significant - specially as you don't have to tab down too much to get that lift.
Another idea is to bolt/glue 3" by 2" timbers on the chine edge for about 8 feet from the stern forward. This gives a huge amouint of lift. Finally, there's a firm called "Speedrails" which makes GRP posh versions of the timber thing. They are in Florida but they have a web site & the guy there is helpful on the phone.
I would try extra tabbing before repitching props.
Also - talk to Mike Bellamy at Lancing Marine - a great bloke & really interested in what's going on.

Thanks Andrew... I'll try increasing the tabs - a previous response suggested that on a 26 foot boat you should have 26" tabs - well mine are only 12"! I have a bit of ali plate that I will try temporarily.. if that makes a difference I'll got some new ones made up!
Thanks to everybody for their responses on this issue!
