    Jim's Ride plate and silicon

    I had my dealer install Jim's Ride Plate last year on my Ultra and I only gained 0.5mph. I though this was odd since other people were posting 1.5mph - 3mph gain. Today was the first time I was actually able to crawl under my ski and feel if the ride plate was trued to the hull. Well, it was... but I did feel quite a bit of excess silicon from the dealer installing the ride plate. I wonder how much of an affect the silicon would have. I mentioned this to the dealer but he claims it would have no effect at all and said it would be damn near impossible to remove at this time. Any ideas?

    Phil,
    The silicone you saw was on the pump shoe.....not the ride plate. There is
    no excess silicone on rideplate or intake grate. Pump shoe is installed at
    factory. Silicone seal on leading edge and side edges of rideplate are not excessive at all. In my opion filling bolt holes with silicone will give you natta in added speed, but hey that's only my opion. Removing silicone from the sides
    (on bottom) of pump shoe is time consuming not impossible, but will not be covered under warranty. If you do clean it off I'd be supprised to see any measurable speed increase.

    By the way, the blue 250 I rode last year with you is today turning 7830 rpm. The customer just called me to report.

    Wow, 7,850 would get me about 67mph! Is the customer getting these rpms on our lake? Why do you think he is getting so much better rpms then I am?

    Phil,
    That's about what mine was turning when it was stock and it would run 67.5 all day long.

    Ed, I never suggested filling the bolt holes with silicone, that would be very bad and do nothing like you say. It might even be detrimental creating more imperfections in the hull surface. JB weld is the way to go. It’s hard and you can sand it flat to make a smooth finish. They say you should put a small piece of rope around the nuts first before you use the JB weld, so you can get at them if you have to remove the JB weld.
