I just purchased a used boat. The motor has very good compression even
though it is an older motor. I ran the boat and it seems the top speed is
around 25 MPH. at 4500 RPM. I would like to increase this speed slightly.
Here is the boat specs:
Boat is homemade from a mold of a Boston Whaler hull. so hull is shaped
like a Whaler.
Hull Material is fiberglass
Length 17 foot
Motor is a 1984 Envinrude 70 HP with a 3 blade 13.25 X 17 prop.
My question is what size prop pitch should I try to go to achieve higher top
end.
