The Stand Up PWC Dolly from Extreme Max is an excellent way to maneuver and store your PWC when it's off the water. The dolly features large caster wheels that make it easy to roll around in your garage, shop or storage shed, and the bunks offer an assortment of width settings to give you the best fit for your PWC. The dolly height is set at 19", making it a very similar height to standard low-slung PWC trailers and allowing an easy transfer between the two.
