i think what he is saying is the top ski in his post beat him on his ski the bottom one in his post. he wants to know why his ski, the bottom one, was getting beat by the other ski at the top.

For racing, your prop is too short.

For racing, your prop is too short.

but the other is even shorter.
rider perhaps?
or tuning?
or single carb?
or a number of variables.

It takes more than a fast ski to race, and it takes a damn good driver to win!!
If you cant keep the throttle pinned 90% of the time your prolly going to lose.
Remember that.

i am pretty sure 12-17 is lower pitch than 13-18 and i am pretty sure the posters ski is set up for freestyle more than racing but i am not an expert

For racing, your prop is too short.

To short for what kind of racing?
Thats a good prop for Closed Course racing. Heck I race with a 10/16 in my blaster.

Really?

I would have gone with a 13/22 with that much power.

could someone tell me why

You have to tell us how you were loosing so we can tell you why if that makes any sense. Was this a calm water drag race in a straight line and his ski was just all around faster, or was the water choppy and you couldn't stay hooked up and on the throttle but he could, or was this a buoy course race?

More details=better answers :beerchug:

 

[Motorheads5]

It's very simple if you want to race buy a SXR if you want to ride buy a Superjet DUH Hell even I know this much lol

could be a drag race.

 

[iptamenos]

the water was like a pool ,no waves at all no wind
we started in our knees
i can't imagine what was the reason
the plate ? the hood (no enough air ) ? the dual 38 carbs (no jetting )?????

 

[iptamenos]

straught line ...... 150 meters

was not the rider my engine wasn't fast???/

 

[QuickMick]

you were correct.

Yea go with a larger prop if its all top end. Make sure your HIGH jetting is correct before you smoke a piston though.

 

[iptamenos]

was the jetting .
