This propeller mounting kit from Polastorm is a complete hardware kit for mounting and securing a WaterGrip-compatible propeller on Suzuki outboards. The kit is intended for 150-300 hp 4-stroke engines with a 4-3/4" gearcase and a 15-spline propeller shaft.
The mounting kit is used with propellers featuring a pressed-in rubber hub and is designed for an OEM-compatible WaterGrip installation. It is important to verify that the engine has a WaterGrip configuration, as Suzuki also uses a different hardware setup for Non-WaterGrip installations in the same power range.
The kit consists of five parts: thrust washer, spacer, flat washer, castle nut, and cotter pin. The rubber hub bushing is not a separate part of the kit, as it is pressed into the compatible propeller.
Compatible engine models
The WaterGrip group includes the Suzuki DF150A, DF150AP, DF175, DF175AP, DF200, DF200A, DF200AP, DF250AP, and DF300AP. Compatibility requires a 4-3/4" gearcase, 15-spline propeller shaft, and WaterGrip installation. The kit is not documented for the DF300B/DF350A with counter-rotating dual propeller system.
