Optimized prop for Lund Fury 1625 XL w/60hp Bigfoot

[Miked3]

Hello all,

I have been reading as much as I can but need a more experienced opinion based on my testing results. I would like to optimize my max top end speed and RPM's. Data below was recorded using Vesselview.

Boat- 2014 Lund Fury 1625 XL
Motor- 2014 Mercury 60hp 4 stroke elpt
Prop- SPITFIRE PONTOON (13.8 X 13") MERCURY RH PROPELLER, 48-8M8026570 - 4 blade

Weight with test numbers is 1332lbs @ 29.5mph @5700rpm. This is with no gear and just me. I will be adding a trolling motor and battery up front along with other gear and a heavyweight fishing partner. Estimation with a normal fully loaded boat will be about 1900-2000lbs. Unfortunately, I can't load up the boat that heavy right now to test it.
With my base numbers and prop, the Mercury slip calculator comes out to a dead 0!

Would love to hear others opinions that have a lot more experience in this area than myself on what new prop direction to go with. I am open to stainless steel as well for that little extra help.

Thanks,
Mike

Motor is a Bigfoot with 2.33 gears.

The motor is also aligned so the cavitation plate is inline with the bottom of the transom.

You or anyone else would be guessing right now, so why not wait until you can get precise weight and rpm readings ?? I can tell you one thing....that motor wont last long at 5700 rpm....

It will be too late basically by the time it's ready to go but I could load it up with 50lb bags of salt I suppose.

It has 117 hours on it running up to 5700. Manufacturer recommended RPM is 5500-6000... Why do you think it won't last long?
