    Riva Ultra 250/260 rideplate on the 300/310

    A few guys have tried it Ive read on here,I'm gonna possibly get one real cheap from someone ,how much speed did you pick up with it ,how's the rough water feel as oppose to other plates?

    I like the deep grooves and skegs of the plate ,looks like a R&D and Riva design mix .It gives me an excuse to install the Candoo speedometer GPS module now that you can't mount the speedo wheel on the plate..

    JetDave, I think the question that should be asked first is "what will this do to the Ski's handling"? This is one plate I did not like in the ocean . . . made the Ski way to bounce-ish for me. I guess on flat water it wouldn't matter. JB

    Agreed, its not really good for much but speed. 1-2mph maybe a little more. Push's the nose real hard in the corner unless trimmed all the way down, unhooks quite a bit more in the choppy water..... but it is faster. You still have to notch a groove in the plate to make it clear your nozzle. Ill post a pic when I get home

    Yes Mike you have mentioned the additional speed with it before ,now wondering what combo intake grate and prop would work best,I'm presently running a stock plate,grate and a prop with a steeper trailing pitch..

    For $100 I play with it but wouldn't trade rough water hook up for a little more flat water speed , might end up putting it with my collection of paperweights and antiques..

    Is the new RIVA plate the Same way, where it helps nothing but speed? Or is it a more balanced design that will help my handling, too?

    Team kawasaki used Riva plate on the 250 platform in offshore application with 1/4" of shimming on rear plate to keep the nose down. Saw it at a race in lauderdale.

    Yep ,this longer plates on the tail like R&D and Rivas raise the bow too much ,with trimming down on the 300 might counter that but yes was gonna throw thick washers on the back bosses to shim down the plate a bit and see what results are...

    Did this with my GPR with a R&D plate a few yrs ago and it took away the bounce and speed stayed the same..

    The shims were more then likely to get the clearance on the plate to nozzle rather than having to grind on the plate
