    Is there a way to make a seadoo speedometer read faster than 70 mph ?

    Seems like my rxp-x & my rxp speedometer dont go over 70 mph, they both have riva mods done to them so I would assume they are quicker than a factory set up ski. I have ran with other skis that are making out at 70 and am clearly faster than they are, is there some adjustment I have missed or are the speedo's only good till 70 mph.

    They stop at 70. Only way to get real speed #'s is with a GPS.

    It would be pointless for them to read past this anyways, they are already unaccurate enough at that speed. My ski reads 70 mph on speedo while doing about 63-64 on gps..

    If you haven't figured it out yet. the USCG could care less if a boat goes over 70. That number is the limit for a PWC's.

    I believe that everything still works beyond 70 mph, but the water doesn't hit the wheel faster than 70 due to the hull shape and planing characteristics. I imagine you could put bigger paddles or move the wheel to make it work.

    Take an air hose to it, you can spin it as fast as you want, not going over 70. Take a speeder gauge and it will go over 70. therefor the limiting factor is in the guages. The wheel is a crappy design that has a huge margin for error to start with. It is like spinning your tires on pavement but reversed. Speedo says your going fast but the car isn't going anywhere.

    I've never done it, but I thought people used air hoses and they did read over 70. Also, I remember someone posting a pic of their on the water showing over 70.
