Rudder Stuffing Gland

The rudder stuffing gland is part of the assembly where the rudders emerge from the bottom of your yacht. The shaft 
stuffing gland should not leak any water. If a leak develops, it can usually be stopped by tightening the packing gland 
nuts slightly. If stuffing gland leakage becomes excessive, packing replacement can be performed as follows:

1.

Remove your yacht from the water.

2.

Loosen the packing gland nuts and back the packing gland from 
the sleeve.

3.

Remove the old packing and wrap new packing around the shaft.

4.

Cut the rings with a razor blade at an angle approximately 30 degrees to 
the long axis of the shaft.

5.

Stagger the ends of each ring around the shaft and insure that the ring 
are at the bottom in the sleeve.

6.

Tighten the packing gland nuts until resistance is felt.

Shifter/Throttle System

The shifter throttle controls are located at the helm station. We strongly recommend you read the operating instruc-
tions outlined in your Owner’s Manual.
