    GP1200r runs but bogs out at 1/2-3/4 throttle only

    1200r starts up and idles great but in the water it bogs at 1/2-3/4 throttle. Sometimes it catches and makes it to 30mph then just shuts down. Restarts no problem. I'm certain it's a lean out condition bc it's high winding sound and not the bog out w/ black smoke. Only thing I can think of is carb rebuild. Couple of things: Cat is out and D-plate installed so it's not failed cat. Brian

    Always do the basic test when having trouble with these 2 strokes. Compression test. Fuel filter and carbs getting fuel. Power valves opening and closing properly. Look for any 2 stroke oil in the hull. Pull caps off power valve and visually inspect and clean the powervalve and install waveater clips. Check valve on top of fuel tank. If everything checks out then pull carbs and go through them.
