Just bought a 1996 ZXI 750 today. The trim gauge says its down. When you press the up tab, makes no noise, doesnt move. top speed of the ski as is is 45mph... i weigh 150lbs. And this ski has mods. Guy says it will run 60 and i believe if the trim werent stuck down it would... Any ideas? im thinking it cant be the trim motor because it doesnt make any noise at all. Maybe fuse? or battery connection? I would appreciate any help thanks.
