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.

A tachometer will tell you more about the trim than any gauge on your dash.

A tach is fine for optimizing flat water trim. The real challenge is
when conditions start to get a bit gnarly and you're trying to
optimize speed vs ride quality while minimizing spray.

After hooking up the laptop to my Yamaha, I wonder how accurate a tach
really is. Somebody is lying.,

It may be a general idea if "this is better than that" but I would not
take the reading as gospel.

I think that I'd tend to believe the computer but who knows. I have a
digital hand tach somewhere in my tool collection if you want to
borrow it and get a third opinion. First you stick a reflective dot
on the flywheel and then the tach strobes it out.
