The panther did not sell so I guess Im going to add some power and swim platform and some k-planes.What would you guys suggest I want to keep it dependable but want the sound of big cams and a good 75mph.This is a awesome boat that rides like nothing I have never owned.I just need to make it fast and update it.

Get K-planes on it if you plan on running over 70. They are like adding a few extra feet!
Are you running bravos? 330 or 365 hp? I think you are going to need to be near 500hp/engine to run 75 w/ bravos more with trs.

I just sold my panther Tuesday and I had 500 hp motors, TRS drives, external steering, k-planes and the boat had a best of 76 mph but usually ran 74 mph and cruised at 52mph at 3600.

If you can believe it I sold it wednsday now Im looking for different one

Panther what props worked best for your setup?

The props that worked the best was 27p Mirage it did not come out of the water that good but cruising speeds was 5mph over 24p 4 blades also tried 25p 3 blades no big difference there.
