The PropPro is the only product on the market that is a snap to use, in and out of the water. Simply push the PropPro on a NON-spinning boat propeller and the proprietary retention plates hold it secure. Apply the included strap when towing at highway speeds or in windy conditions, or in the water in strong currents or wavy conditions.
*The strap may be needed in normal conditions on some smaller propellers.
**Please note that the top and bottom grooves double as 1) a skag groove for applying the PropPro to out-drives with skags that may impeded application and 2) rotate the PropPro so the groves are on the sides and route the strap through these grooves. See PropPro Strap Application video below.
***The interior retention plates are replaceable. See the "how-to" videos below.
