GRP (polyester) stern tube suitable for a water-lubricated propeller shaft assembly.
The shaft tube, which is provided with a cutless bearing, must be bonded directly into the hull.
A propeller nut with integrated zinc anode comes as standard with the propeller shaft(option).
There are two options, for water lubrication of the shaft assembly:
By tapping a small amount of water from the main engine’s raw water-cooling circuit.
For the second option, we offer the ZWBKIT. With this kit you have all you need to water-lubricate your shaft assembly by using water from the main engine’s raw water-cooling circuit.
The kit consists of a T-piece(18-10-18mm), 3m of 10 mm diameter hose (DWHOSE10A) and four hose clamps.
