R&D Marine 6" Short Solid Half Coupling Pilot Bored

Part No: 808600

This solid half coupling is machined from solid steel and mates with the gearbox output coupling to connect a boat propeller shaft to the gearbox, usually via a flexible coupling. This solid shaft half coupling is pilot bored and needs to be machined to suit the boat propeller shaft diameter.

Typical applications include:

6" nominal gearbox flanges of Newage PRM, Borgwarner Velvet Drive, ZF - Hurth gearboxes.

Replaces PRM coupling MT783
