Are you getting the most speed out of your ski you can?

I have seen a fZR tunnel split bad on a sk that was only running 74 mph and had never seen any rough water conditions at all. Tommy Jordan

I'm very interested in what people think the mechanism is whereby the ski is faster on fresh water compared to seawater. Now, disclaimer, I don't chase top speed much, so don't have a lot of personal data, but had always assumed that sea/salt water, being of a higher density, would be quicker. This is due to greater buoyancy (4-5%) making the ski ride higher and thus less wetted surface drag, and the higher density through the pump giving a greater impulse (momentum change), fairly important at top speed, since as speed increases thrust decreases, assuming the same exit nozzle velocity...

This is genuine curiosity, not disputing anyone's experiences.... I know I get more speed on salt, but it's hard to separate the engine's performance gain going from the fresh water lake where I usually ride @ 3000' AMSL down to sea level (10% more air) from the water induced factors...

Always assuming water conditions the same, of course.... I've never had the pleasure of glass on seawater...

Hitman, what did your final prop pitch come to, to get to 81.9?

I agree whit zone5 Or at least our raceboat is quicker on salt water than fresh water.
