For an 85 HP, 12 3/4 sounds like the prop diameter. What is the pitch of the prop and how many RPM's does your motor turn at full throttle? This info will help calculate top speed. OR. how much does your boat weigh when you are loaded up for fishing and what kind of hull--deep-V, semi-V or whatever? Is motor an OMC?

Here are the specs on the prop, 12 3/4 x 22. Fiber glass boat, not sure of the weight. the hull is V but does have a liking of a tri hull. Motor is a OMC. I have no tachometer so i have no clue what the rpms are..........Not much help am I

Well, guessing the weight of your boat at 1200 lbs, you should get about 40 MPH.
