Puny trim tabs, and no fuel shut-off valves were the only gripes I've had about my 2510. The fuel shut-off valve problem was easy to fix in a couple of hours.
I ended up overcoming the puny tabs by placing Cobra Marine trim plates on each of my F115s. The plates are solid SS, and bolt to the bottom of the anti-ventilation plate of the motor. They are stronger than the hydrofoils that bolt to the top or the ends of the plates (which end up causing the plates to crack and break). With the addition of the plates, the trim tabs are much more sensitive.
Parker should have put larger trim tabs on the 25' hull. Have told them so several times, but I don't think they listen to me very much.
