    Sealing deck hardware

    I removed cleats and chocks for fiberglass refinishing. They all had studs through the deck with no evidence of a gasket or sealant, nor evidence of water getting through the holes. I put them back on without sealant, but am now having second thoughts, thinking I should remove them and seal with...

    Speedometer Needle Bounces

    Since the boat (97 Wake Challenger Merc inboard) was new, the speedometer needle has been steady up to 22mph or so, and then bounces wildly at speeds higher than that. The pitot tube appears to be clear and the inlet is right at 1.5" below the hull. I blew air into the tube at varying...
