ABSTRACT:
A marine drive water pump impeller (1) is provided for a marine rotary vane positive displacement water pump. A filament wound annular drive hub (3) is cured with resin polymer. A rubber annular base (6) having a plurality of flexible radial vanes (7), is molded in place around the drive hub (3). The resin polymer and the rubber are compatible and enable substantial bond strength therebetween. The hub (3) is wound in the circumferential hoop direction, providing substantial hub strength. The invention overcomes frozen water pump problems in marine drives used in freezing environments.
