I've got a 2007 Bayliner discovery 195 with the mercruiser sterndrive 3.0 (135hp). It has the 14.5 prop at 21 pitch. It is the basic black painted aluminum 3 blade. My engines WOT is 4400-4800. With this prop, it will rev up to 5,150 rpm if I test its max in the water. What can I use to gain some usuable speed (understood I lose some hole shot) so it will let me ride at a higher speed at regular rpm?
