Thread: Yamaha gp760x

    Yamaha gp760x

    Hey all!!!! I recently picked up a very clean GP760x with a blown motor. It was only 400.00 so I figure ill throw in a quick SBT motor and have an additional play toy for summer.

    Can anyone give me the god bad and ugly of this make / model. Is there anything specific to look for regarding wear replacement. Im more familiar with seadoo so this is my first run with a Yamaha.

    Thanks

    My first ski. Normally very bullet-proof motor.
    Porpoising big problem, found discontinued aftermarket ride plate here on Hulk, helped a bunch.
    Cold-blooded. I would remove a plug or two and put a few drops of fuel in the cylinder before trying to fire up cold. Three times max to get it running.

    everything was fine until you mention S.B.T. their motors are a big P.O.S . this will be the only bad/ugly of your model.

    What year is it? You may have original plastic trim tabs that are broken.

    OK, no trim tabs at all on yours, in fact I just made some for ours. Common problem on those would be the pipe mounts coming loose and the center pipe section cracking.

    Thanks everyone for the help..... Out of curiosity if SBT is not your drink of choice who would you recommend. I personally rebuilt my last seadoo motor but would prefer to just swap one out for this machine.

    thanks

    Okay last question... Is there a larger bolt in engine for this ski. The stock 90 hp isnt exactly blazing. I understand anything will fit with a lot of work. Im looking for more of a bolt in swap.

    thanks

    a the gp760 hull is the same as a gp800 and a gp 1200 hull. just have the motor mounts mounted in different locations, but the inserts are still there so you can move the mounts around in the hull.

    I have a 99 gp800 that I pulled the motor out of to put in a stand up, but still wanted a sit down to set up a buoy course and rip every once in awhile. So I move the front motor mounts back to the 701/760 mounting location. grabbed a 701 motor off the shelf with a taber bored 44 protec carb and a westcoast exhaust and threw it in the Gp800 hull. put a 10/18 skat in the pump with a riva extended rideplate and a set of beach house sponsons. it is a great little ride! Slow but the handling is amazing compared to stock

    So you can easily do the reverse route. If you want I have a complete gp800 engine minus the carbs, but you could use the ones off the gp760 engine because I have a brand new ADA manifold to go with it!
