Quick prop question

[joeyd50]

Quick question guys, I have a 1986 Skeeter Starfire 175 bass boat 18.5 feet with a 1975 85HP Johnson, my top speed is 32.6 MPH according to my GPS, the motor is running at 5500 RPM with a 13X19 prop, is this the best I can expect?
Thanks
Joe

Re: Quick prop question

Probably -- unless you play with setup. Where is the AV plate on the engine in relation to the bottom of the hull? If its even or below, raise the engine a hole and try. You might pick up a MPH or two. Less engine in the water = less drag.
