Port side has steady drip. Gonna haul the boat should I replace starboard side seal too even if it's not leaking? I have no idea how old they are boat is a 2002. How long do they usually last? 2nd question...CAT 3126 TAs 420 HP turn rated 2800 wot. Should I take out an inch of pitch to shoot for 2850-2875 to reduce the load through operating RPMs as boat gets loaded/dirty bottom as suggested on boat deisil web site? Now would be the time to do it if I was going to. Any opinions on pitching props for more than rated rpm? I want yo do right by these 1800 hour motors, but don't want to just waste money if not needed.
