I have a 2000 cougar with a 225 about the same top end. Are you using your trim at all at mid range? Mid range being about 4300, on mine this is about 48-50. my prop is about 2 3/4 below. I dont think that a hydraulic plate will help where you want help, it will help in shallow water and getting the last mph at the high end a little. But am sure others will cime in. Unless you are loaded very front heavy my guess is you need to trim a little more at mid range speeds.Irv

What is your water pressure at WOT?If it is good I would raise the plate 1/4″ increments and see if you can get your rpms up.I own a puma ftd with a 250 and thanks to a good friend get to drive a cougar ae with a 225 proxs often.It aint right til you can get that bad boy to turn 6000.I would expect you to be able to turn that wheel on that boat as the cougar AE I get to drive occasionally is loaded to the gills and I had no problem getting 71-72 yesterday with great lift midrange while also carrying 3/4 full of gas and livewells full.In regards to the plate thing- I have owned both. The only things I like about a hydraulic plate is being able to floor that plate in big waves to avoid prop slip and raise it way up on idling into skinny water.In terms of running the boat it doesnt really help that much day to day.C.O.D.

Manually wrenching up 1/4″ increased 29-47 RPMs per the different props and pitch. My speed gained about 1.2 to 1.5 mph.
