Soooo.... I'm at 3.25 below the pad, 27" Yamaha T1 prop, turning 5850rpm and GPS Speed best is 69.8, usually turning 5750-5800 at 68.x-69.x mph... Water pressure came up actually when I raised the plate last time, running 22+psi at WOT... 12" Slidemaster Plate, no spacers or wedges...

According to the prop slip calculator, I'm running about 13% slip... Guys in my club were commenting on how high my rooster tail was last weekend...

So, It would seem that I need to come up more on the plate, but would prefer to get close this time and fine tune from there...

3.25" below seemed reasonable, but what is realistic for coming up, should I jump a 1/2", 3/4" or a full inch?

I think you could go to 2.5 and start going up a 1/4 inch at a time from there

I've got the same boat/motor and am running a 27 tempest plus (I think thats the right one, it's the 3 blade one) and run about 70 fully loaded with a partner and livewells full. Running solo, I can get about 75.

13% is pretty good. most goals are set to be at 10%. i bet your over-trimming with that high of tail. bump her own some to about 3/4 when WFO. should pick up some speed and loose a few rpms. I would also hang around the 3" below pad area unles you got to a different prop or have the current one worked
