Center of gravity and placement on a trailer

[97SPX]

Does anyone know how to determine the center of gravity of a seadoo? I'm about to swap two seadoos between two single trailers to put the larger one on the larger trailer. Both have adjustable winch locations so I need to figure out where each seadoo needs to sit on the trailer in order to be properly balanced for towing. Any suggestions?

Thanks,

I never worried about that, but if you have the room, I'd pull the ski up enough, so the pump assy/nozzle was inside the back crossmember of trailer. (assurance of being bumped, wont f-up the ski...)

put on trailer not all the way forward and unhook the trailer. now, crank the ski forward until you have about 50 lbs on the tongue. it isn't real critical since these things are so light. you don't need to hit the 10% of the weight on the tongue number you want with 2000 lb on up trailers. but it should be heavy enough to stay down, and not so heavy it is hard to pick up and move around.
