hi everyone im new to pwc and to the forum. i bought a 2005 rxt last weekend went to the lake and it works fine, tons of power. went to a differnet lake the next day and a friend docked it on top of some rocks and after that it ran like crap. he didnt admit to doing it untill after but it vibrates really bad now and wont go anywhere. i think i got all the rocks out but havent tryed to ride it again. any tips on what i need to do or look for?
