I have a Bayliner 2750 with 12"X8" trim tabs. According to this:

and this:

they should be 18" X 12". I don't know what the implication of that is (slower getting up on plane?, not as responsive at slower speeds?), but I do know that a tiny adjustment at 25mph makes a big difference in the attitude of the boat (I've put in Bennett Auto-levelers so that solved that problem). I don't think they do anything at no wake or just above that but they do make a difference in getting up on plane.
It's not worth it to me to upgrade to a whole new system ($500+) but I wondered if I could pop rivet or weld larger tabs on the existing plates. The pump is from "Boat Leveler Mfg Co. I can't get a serial number or model, but I attached a picture of the pump reservoir. The issues I see are whether the pump/pistons could handle the larger tabs, and if the pop rivets would introduce enough drag to be an issue. Also, the tabs would be lower by the amount of their thickness. I just don't know if it would be worth it. Better control at lower speeds wouldn't hurt and getting up on plane faster wouldn't hurt either.
