I would like to hear some suggestions on which prop would be best for my boat motor set up. I have a 06 Puma 225 Pro XS. The prop on the motor is a Tempest plus 27 p. It seems to me to be a little to much. I am thinking possibly a 26p trophy plus. Also how much should the water pressure be at about 4500 rpm and at wot. Thanks for any help.
