After reading and reading , can somebody make it easy without any math. I understand there are so many variables, but laymens terms will help me out before I try changing props.
Thanks.
Boat: 1966 Champion
Length: 17'
Motor: new 351 ford
Hp: 280+
RPM's @WOT: 5300 (need to be below 5000)
Outdrive: 280 volvo
Prop Now: 14x22 Lh 3 blade stainless
New prop: 16x17 Lh 3 blade stainless
So now for the question: Needing to bring down my rpm's, and in theory or experience what will the new prop do in comparison performance wise to the prop on it now.
