Harry,
Compared to your 36' Lobster Boat, my boat is small. Now that I know what
is the proper trim, I use my gauges, but when I first went out in the boat,
I figured out what the correct trim was by listening to the sound of the
engine and prop.

The tone change is higher, like the prop is starting to come out of the

difference.

Why don't you just say, "sorry, I can't help you, because I just don't
know."



Smithers must have a pretty small boat. I can't hear "the tone" of my
Yamaha while I am in the cabin of Yo Ho. Instead, I rely on the electronic
trim gauge Yamaha thoughtfully provided, along with the tach, the GPS, and
the current wave conditions to determine "proper" trim.
