[QUOTE="Randaln, post: 495592, member: 28926"] Moe da lawn your correct on the repitching Prop.. we only can change the outter 1/3 of the blade mostly.. And that’s where the speed comes from.. I have changed a 13 down to a 9 On a alm merc prop But I had to (cut )and heat prop next to exhaust hub barrel area and reweld..after Repitching Or it would of cracked blade right off.. This was on a 25 merc 2 stroke On a nitro fiberglass bass boat. 16 -17’ It did alot better .. Instead of just plowing water , And taking forever to get on plane.. So yes it’s only advisable to repitch 2 degrees up or down.. I did that work on a buddy’s prop that agreed that if I snapped a blade off I wouldn’t have to rebuy him a new prop.. [/QUOTE]
