My Carver 26 (recently bought, discovering many things) seems to have an Insta-trim boat leveler pump. The red cover is still there, but the bottom white part (reservoir?) is missing and I noticed a sharp corner in a pressure line... So that one has a disappointing history and does not work any more. My question; is it worth to replace the pump or should I install a different type of trim tabs control (no pump, manual position, different brand pump) general question: how does the trim tab and the heckdrive position trimming work together? We will seldomly be able to go so fast to get her into plane but when I'm at it (overhaul everything) anyway, I'd like to do the job well. Within reasonable cost. Any tips welcome.
