"I have a friend and he wants
"I have a friend and he wants more power from his 1965 75hp V4 Evinrude. He has three 10 X 10 1/2 props. He is thinking of having one re-pitched to 10 and the other re-pitched to 9 1/2. He wants a variety for speed and pulling power for skiing. It is on an old 1972 Sears 15' fiberglass boat. Not a rocketship nor is it light weight. He builds and races cars and is thinking of milled the heads, perhaps opening up the exhaust ports, advancing the timing, etc.
We know years ago they used to hop up these old Evinrudes to make more power.
What did they do to them and what can we do to his easily?
Any and all suggestions will be welcome.
Thanks.
