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.

I had a similar problem on my 1990 OMC Cobra. What could be easier.
Remove the trim tab indicator and replace. My idea was to check the
sender when it was off the drive.

Not a good idea. The bolts snapped. So I had to drill and tap the
holes again. Then when I did check it, it worked fine.

It's easy to check using the procedure the other posters have
suggested. But it might not be easy to change. For one thing the
wires that run through the hull into the engine compartment may not
pull through. Mine won't. I've postings in other locations where the
owner put an new indicator on by trying to make waterproof splices in
the wire. Not always succesfully.

Good Luck
