I have a 44' Ocean Alexander with the Caterpillar 3208's turbocharged engines. The build sheet that came from OA show the 25x17(?) props I have came from the factory.
When I go to the Caterpillar website they indicate the maximum engine RPM's for the 3208 should be 2800, but I only get 2400 at WOT. I've been told that means I'm over propped.
I've read and heard that cruising RPM's should be 75% of WOT. So here is my question, should I cruise at 1800 RPM, 75% of 2400, my engines maximum or should I bump it up to 2100 RPM which is 75% of what the engines should turn?
