I have a bowrider with a 300HP Merc and Bravo-1. After bringing the
boat home from dry winter storage, my trim sender seems to be faulty.
When raising the drive, the needle on the dash goes from full-in to
full-out in one qick movement as the drive is raising slowly. I'm
assuming some problem with the sender on the lower unit.

How easy is this to repair? It is a 2002 boat/engine. It may be
under warranty, but if it's easy I'd rather do it in the driveway on
the trailer than haul it to the dealer.
