Hi,

I own a 1942 Wheeler (83 cutter from WWII) and am interested in learning
about prop design. My engines are 250 HP Cummings with Twin Disc Gears. My
goal is higher speed with lower fuel consumption without causing damage to
the drives. I know that the current props are 4 blade and generate 10 mph
at 12-1400 RPM depending on current and wind. My current fuel consumption
is 1.1 gallon per mile. The weight of the boat is 80 tons and is a
displacement hull.

Thanks for your help,

Marshall
