    How To: Plugging rideplate holes for more speed

    This was submitted by Drink My Dust from my Yamaha forum.

    Don't forget to plug them bolt holes for some extra mph.

    I'm going to post the pics of the putty that we all got introduced to at Mud Bug #1.....this stuff was being used by none other than Tommy Jordan on his ski and with his permission I am passing on one of his tips that need not be forgotten.

    The first two pics are the recommended putty to fill in the ride-plate holes





    The second two pics are of holes that have had this in......but removed so you can see the layering process.

    First take a strand of nylon rope and circle the bolt head.

    Second take a patch of duct tape and stick to bolt head and rope (this will hold the rope in place and protect the bolt head from the putty adhering to it.

    Third Apply putty to fill in the rest of the hole and sand smooth at end of process......stroke the sanding front to back of hull......not side to side.

    Fourth......go out and GPS anywhere from .5-1.0 mph gains and wipe that smirk off your face. Some have reported as much as 1.5 mph gains with this.......but I'd say .5-1.0 is average. When/if you need to remove the putty......simply tap with a screwdriver head a few time......out it all pops.

    Here are the pics of the layers. The stuff is super easy to work with

    Enjoy.............

    I used Magnum Marine Epoxy from Loew's. Cheap and works great.

    I filled 1 holes as a test to see how it will turn out as per your istructions GH. turned out good.Then wanted to see how it will come out if i ever need to remove the ride plate or intake grate.
    It was a pain in the arrrrssssss to remove i used a small hamer with a chissel, i dented the bolt a bit and i took my time removing it.

    where did i go wrong ?

    If you got the plug out you didnt go wrong

    Yea, its a pain in the ass to get them out, but it is possible.

    On the bright side, i have never heard of anyone having to remove their ride plate

    thanks jerry ,always helpful.
    it was possible to take it out ,but was a long process and i scratched the ride plate hole inside also.
    and it is very rare to need to remove the ride plate especially for fresh water use.
    what about the intake grate bolts?those are not uncommun to remove once in a while(like a rope getting tangled in the shaft)and needing to remove it on the beach.
    instead of the hard marine epoxy.can i use the black silicon that they use around the ride plate?with the rope technique and tape.
    thank you

    I always use Permatex "Right Stuff" silicone for the grate holes.

    On the intake grate bolts I used a small piece of aluminum foil to cover the entire bolt head and sides, and then used Magnum Marine epoxy from Loews to cover the holes.

    The trick to removing the plugs is to use the chissel at a 45 degree angle, tap it in the middle and comes right out in one piece.
