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 and ZF - Hurth gearboxes.

Coupling dimensions:

a - Flange outside diameter = 5.75"

b - Hole pitch circle = 4.75"

c - Number of holes = 6

d - Hole size = 0.50"

e - Register diameter = 3.00" male

f - Coupling length = 5.87"

g - Coupling boss diameter = 3.65"

h - Pilot bore diameter: 21mm (for customer machining to parallel or taper as required.)
