That makes a lot of sense. Catalac's (at least my 8m) seem to get easily to about 4 kts, and then need a lot more push to get past 6kts. I did a lot of prop testing with my yamaha 20 Hp when I first got it to try and match the engine to the boat. I now think I made a mistake in not getting the high thrust 9.9 yamaha, but eventually I I managed to get a reasonable compromise. The graphs are in the archive section.
