Steering & Shift/Throttle System
Your yacht is equipped with a manual hydraulic steering system.This system will operate differently from a car's
power steering system.
• A rhythmic pulsing when turning the wheel is a characteristic of the pump and is not a malfunction. Also, when
coming off a hard-over position, resistances may be felt, followed by a distinct sound. This is a normal situation
resulting from the release of the system's check valve.
• The fluid reservoir for the hydraulic steering system is located in the rear machinery compartment. Check the fluid
levels and pressure regularly.
Rudder Stuffing Gland
The rudder stuffing gland is part of the assembly where the rudders emerge from the bottom of the boat. 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. Do not over tighten the packing gland nuts. If stuffing gland leakage becomes excessive, packing
replacement can be performed as follows:
1. Remove the boat from the water.
2. Loosen the packing gland nuts and back the packing gland from the sleeve.
3. Remove the old packing.
4. Wrap new packing around the shaft.
5. Cut the rings with a razor blade at an angle approximately 30 degrees to the long axis of the shaft.
6. Stagger the ends of each ring around the shaft and insure that the rings are at the bottom in the sleeve.
7. Tighten the packing gland nuts until resistance is felt.

Trim Tabs

The trim tabs may be used to help keep your boat level at cruising speeds.
The trim tabs are controlled by two rocker switches at each helm station.
Before using the trim tab rocker switches, read and understand the trim
tab operation manual included in your yacht's owner's packet.
Observe the following:
• Once cruising speed is reached, the port or starboard trim switch may
be used (one at a time) to level the boat. Perform trim tab adjustment
with several short touches to the switch rather than one long one. After
each short touch allow several seconds for the hull to react.
