2000 520vx Setup - 225 Opti

[PowerFish]

I installed a 6" slidemaster manual jackplate.

Prior to the jackplate, my 25" Tempest would max out at 59.3 and would not turn it much past 5500 (21% slip), now with the jackplate, I can turn that 25" tempest at 3.25 below pad right to 5700+ but the boat is slow as shit at ~54mph (31% slip). Water pressure is about 24psi at WOT and lose a little pressure in the turns, but not real bad.


I also have a 24" small hub Trophy, I can wind this prop up right to the rev limiter (5750) at 3.5" below pad and running 56.3mph (25% slip). The prop is dinged up so not super worried about top end with that, and a 24" is clearly not enough prop. Before the jackplate, it would turn right to 5700+ and run 58.4gps (22% slip)


So, in short, this Ranger is slower now. 1/4 tank of fuel on port, 3/4 tank of fuel on starboard. Not a crazy amount of tackle in it. I'm getting bad prop slip numbers.


Where do I need to go from here? Love the way the boat lifts and handles with the small hub trophy... Both props need to go in to be cleaned up...

Croxton is a wizard with your setup

Something is WAY off here and it sounds like more than a prop issue. I fished with two different guys for years that ran 520-VX w/ 225 Opti's and they both ran 68+ w/ tournament load on their worst day. They both ran 25" Trophy props w/ 6" Bob's jack plate. Thjeir props were out of the box / no aftermarket work. Your numbers with the 25" Tempest are off also. Are you sure your engine's throttle is fully advancing?

Definitely should be running at least mid 60's with a load and 2 people. Buddy used to have one and I believe it ran 68ish light and 65 with me in the boat. Lifted well.

I have same boat and motor daul consoles , 25 tempest plus.
Light load one power pole , no jack plate best run 71 gps,
now have dual power pole 10’ blades, 8” manual slide master jack plate , heavy tournament load me 270lbs 6’1” and son 5’11”& 235 lbs running 65 gps all the time when running balls out.
so I would say you definitely have something off , maybe take to shop put on scanner see if anything is off and make sure throttle is opening full throttle.
I have hot foot throttle i don’t think that makes a difference, oh I also made a plate that goes on bottom of jack plate so doesn’t catch a bunch of water . I hope you figure it out that would be very frustrating, Good luck
