Hi,
First let me thank you for reading this thread.
I am working on a new wooden fishing boat with the ff: It's a 68 footer with 400hp engine @ 1800rpm, gear ratio 4:1, Displacement of about 150000Ib. I have used two prop calculators and they all recommend 50x45x4 propeller. The problem is a 50inch prop is too large to fit, a 40 inches would fit. I am wondering if a 5 blade is the answer. Your recommendations, PLEASE!!!
