    What does the pitch of props do?

    I’m running a 25 tempest plus 3 blade. I added a lot of extra weight to the ass end on the boat. Should I go up in pitch or go down. I can get hole shot.

    Down. In theory your 25” moves 25 inches per revolution. Smaller prop/pitch increases your wide open throttle (WOT) rpms and gets on plane faster. A smaller pitch, say a 23” only moves 23 inches per revolution, therefore increasing the number of turns while driving.


    A 4 blade tends to give a little quicker holeshot too though. What’s your current WOT rpms with your load and what motor?

    You can google it to get a better understanding if what I wrote above doesn’t make sense.

    A 25 Tempest plus has PVS holes. You can adjust those for better hole shot. What is your current PVS configuration?
