Re: Question on max engine rpm with reduction belt?

Reductions are meant to get the motor into Peak HP Range... Torque means jack **** without RPM. HP is Thrust... the trick is to get the prop in its most efficient sweet spot when HP is peak. In short, if only torque mattered everyone would be running direct drives and turning props at 3000 rpm becau...

Re: Question on max engine rpm with reduction belt?

2500 X 2.3 = 5750 but target 5200-5300 on the motor as the prop will gain 200+/- rpm on the water.

Also what is your engine curve and where does it hit peak HP. That really dictates the target rpm.

Re: What prop, reduction to go with

By the video he topped out at 540hp @ 6000rpm redline. Just depends on what he wants... EX blades are designed for about 2200-2400 rpm. So a 2.5 would give him the full usable rpm range. JX blades are about the same setup. S series or whirlwind superwides he would be good going to a 2.68. Ive always...

Re: Electronic gas pedal for 5.3 ls

Mine is flipped over. Used factory bolts holes to mount in it a box then the box is mounted to the under the foot deck. This way you can move it around and even mount it extended past the foot deck like mine. Plenty of walking room.
