I cannot seem to get more than 5.5 Kts with the 15X9, 2 blade or a 15X10 3 blade both recommended by Catalina. This is at cruising RPMs of 2400 RPMs. I have had the engine checked out and it is putting out 2850 RPM tops under load. The mechanic says the engine is putting out the proper HP and running well. Any recommendations on the correct prop for maximim cruising speed ?
