Re: 1994 mercury 115 rpm
Raising the pitch is going to hurt your hole shot. Where does it run with the live wells full and a 200 lb fishing partner in it? If the numbers you posted are alone and dry, you're about set up for fishing now.
What is your hole shot like. Does it overload the motor, or does the prop slip and not grab good?
I run a high five, which bites in real good, but it's ventilated enough so the XR4 that drives it can spool up to almost 3 grand before it bites. It's a neck snapper.
Engine mounting, and handling the trim can have huge effects on hole shot also.
hope it helps
