Boat came with 25P yamaha prop on a yamaha 200. at WOT it has around 28lbs of water pressure and runs 68mph but I'm hitting the rev limiter. I brought the jack plate up almost even with the hull and tried a 26P prop and still running well over 6000 rpms with high water pressure but not picking up a lot more speed. Any suggestions on what has worked for you or your thoughts?
Somethings not right, I have three different props i run and have never hit the limiter. 25 T1 5800rpms, 25TXP 5800 and 24 Fury 5950 with the prop to pad around 1 to 2 inches below(haven't measured in a while). All three will run 69-70 with myself and a Tx load.
where is your jack plate situated? Do you have the Series 2 3.3L big block or the smaller 2.6 or so motor? Thanks for your help.
I have a TZX 200 with a 200 Yamaha Vmax (OX66)
I have 25M prop.
Do you know what the diameter is for this prop?
I was looking to get another prop but wasn't sure of the diameter.
I've not hit the limiter yet with a stock 25p or a 25 TXP, with the TXP running as high as 1/2" below pad.
Are you sure your tach is right?
