1991 Pantera 2 prop setup

[brinel1521]

New to the forum. I have 1991 p2 with recently installed 2008 optimax 175. The original 200 motor went out and had high five prop. Anybody have any suggestions on prop type and pitch?  Hoping someone has set one of these boats up before and has some experience with props. The high five 25 from my original motor is too much for the new motor.

Grew up in a ‘94 Classic DC that ran a 24” Trophy, but it had a 150HP Suzuki with 2.08 gearing and 6k rpm limit. The 175 Opti has the same 1.87 gearing as the 200 from ‘91, but a slightly higher rev limit of 5750 vs 5600. I remember riding in a P2 with a High 5 back in the day though don’t remember what pitch and would think you could step down 2 pitches given the speed difference and rpm increase of the 175 over 200. The fuel tanks being in the rear in those models I think benefit from the rear lift of the Trophy and the ventilation of small hub I think helps the relatively smaller cubic inch engine get into it’s powerband easier, what mph are you able to run? I’d let you try my 24 Trophy if you were close.

Thanks for the reply. The old 200xri motor had a high five 25p and it ran about 65 in smooth water.  The guy who replaced the motor said that this was too much prop for the new motor as it doesnt have as much power and suggested a Tempest 23. He also suggested about 3.25 PTP as a starting point on the height. I am new to trying adjust motor height and props. I never messed with adjusting the old motor as it was setup when I bought it from original owner and seemed to work . My boat has twin 25 gallon fuel tanks in the back as well as 3 batteries. It is heavy when there is lots of fuel and both live wells full of water. I was hoping someone has set one of these older boats up before and had some good suggestions on what worked for them and would be willing to share.
