    97-99 GP1200 Ride Plate Insert Upgrade

    This is how I Upgraded my Ride plate inserts on my 99 GP 1200. I am sure there are many ways but this worked great for me.

    Items needed

    (2) 05 1300 Pump shoe inserts #F1G-U8571-00-00 from boats.net $8.50 ea.
    (1) package JB weld
    (2) 2" strips of 1/16" x 3/4" aluminum I bought a 4' piece at Home Depot
    (1) tube 3M 5200 fast cure

    Part 1:

    First I had to remove the glue and the one remaining insert and prep the area This was the hardest part. The Yamaha factory glue is a "pita" to remove I asked for help from the forum and was told heat it up with a heat gun and chisel it off with a hammer and chisel. I did this and then sanded the surface for prep.

    Part 2 99 GP1200 Ride plate insert upgrade

    Part 2:

    I modified a 05 GP1300R pump shoe bracket #F1G-U8571-00-00 to fit the bolt hole spacing of the 99 GP1200 it was about 4mm longer than the 99.

    1) I cut the insert in half and ground some material away to get the proper spacing
    2) I used a ride plate as a fixture to hold the two pieces and align them
    3) I cut two pieces of 1/8"x 3/4" aluminum 2" long to use as strenghening ribs when I bond it with JB weld. I drilled some holes in the aluminum to allow the glue to squeze out and insure a good bond.
    4) I applied the JB weld to the supports and clamped it together to cure.

    This took maybe 1/2 an hour of work and is easy to do with basic tools.

    I will add part three installation later this afternoon when I complete. Mine was pretty bad I had the Hex shape of the original insert pulled clear through the bottom of the ski.

    I bought this ski last March I looked it over good and it had a few minor issues I never noticed the ride plate bolts I went to change a prop and was going to remove the ride plate when I found three bolts and a stud with a nut hanging down I went to remove the nut and the whole thing fell out from the hull it was a bolt that was siliconed in the hull what a mess.
    So to get out on the water I had my Son install a bolt from the bottom and I had a nut and washer I held in place inside "PITA" having one of these you know how much stuff you need to remove to get there. I was going to make something then I got the GPR and this sat in the yard. I bought the upgraded inserts for the GPR and they were on my bench so was the 99 ride plate and I checked it out said cool easy fix GPR style. I was considering having it welded but was not sure how it would workout so this was an easy solution.

    Besides you have hit such great numbers lately I might have to hang on to this awhile longer and see what she can do.

    That's great info Osidebill. How does this happan... is it alot of wave jumps and landing on the ride plate, or is this not that common? I just wonder with the last owner that when he placed just a nut and bolt and some silicone that this added more stress to the hull area of the mount as it may not have distributed the load as the stock insert.. maybe?

    I believe the stock inserts go bad from cross threading bolts over tightening bolts etc. I think the shoddy repair is what pulled the bolt through the hull. I have had nothing but issues with fasteners on this boat missing, broken, permanently glued in. it's a challenge every time I remove something new. even the carb adjusters were tight and the throttle adjuster had been loctited just amazing. I know some other members here who have had rideplate inserts spin so I think this is common.

    Just keep it and enjoy it some. It sounds like you have wrenched on it alot and have not had time to enjoy it. Loctite on the idle adjuster? That sure is strange. You are right about it being a pain to work on in the back of the ski. I have been in the back of mine over the years, installing trim tabs and fixing a spinning insert.

    I have had the pump and ride plate off mine, with only one front right insert on the pump that turned,(looking from the back of the ski) lucky this one you can reach from the inside. Have glued it back and is holding, had the pump off twice since then. My trouble was the intake grate, broke 6 out of the eight bolts and when I pulled the pump apart, all 4 pump bolts I rounded the heads off!! Have replaced them with high grade stainless 12mm head bolts. I think really that Yamaha should have used bigger bolts on these parts... maybe all over the ski!

    This method of fixing the mounts seems to be the way to go


    Not looking forward when I rebuild the carbs
