- 2x 205 HP 4.3L V-6, Alpha-1 G-2
I recently swapped out from a 3-blade 15x17 aluminum to a 4-blade 15x16 aluminum.
New prop is a Mercruiser Alpha-4. Cost $130 dollars.
Old cruise of 3,300 rpm was 18-19 mph. New cruise is about 21 mph at the same rpm.
I didn't time it, but the boat planed perceptably faster, and held speed better.
Boat is a 1987 210 Seville II Mid Cabin.
