First I'll drop into a local Mercury dealer to get an estimate on installing a 'trim gauge' and sender pkg.

Why bother, not worth the money in my opinion (and experience). As
others have said, you just need a little practice setting it up for
different conditions. There is no one trim setting that is right all
of the time. The big variables are sea state, boat loading, wind
direction, speed, etc. After a while you can a feel for what bow
angle works best for different conditions and then you adjust the trim
to achieve that angle.
