Prop recommendation for 90 mono

[shoboat]

Doc,

I think the 2615 reduced a little will work just right on a 1.01 motor.

Glad you are testing the new propellers, it is much appreciated.

Thanks,

Mark Sholund

Say what you want DK....But when he burns a hole in the piston...I hope you ears Ring.

Chuck the head volume has nothing to do with burning the Pistons. Lack of fuel delivery does. In the mid 90s I ran a Grand Prix 90 in a seaducer heat raced at 72. Yes faster then still today's boats. On 33% fuel. And never took plugs.

More volume and more clearance is detuning. Believe what you want.

Hi Shane,

I have a 90 Seaducer that I got form Jerry Crowther/ Jeremy Edge. They were running a Back cut X467 on a VAC 91.

I put an old wore out K-90 in the boat and it spins that same prop perfectly. Great handling, good throttle response and good speed.

I tried other props, but that Back cut X467 was the best all around.

Good boating!
