Rudder Stuffing Gland; Trim Tabs - Bayliner 3788 Owner's Manual

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

LOSS OF CONTROL HAZARD!
Improper use of trim tabs may cause loss of control!
• Do not allow anyone unfamiliar with trim tabs to use them.
• Do not use trim tabs in a following sea as they may cause broaching or other unsafe han-
dling characteristics.
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.
Before using the trim tab rocker switches, read and understand the trim tab
operation manual included in your yacht's owner's packet. Always observe
the following:
• Once the best bow cruising trim is reached, the port or starboard trim
switch may be used (one at a time) to level the boat.
• Trim tab adjustment should be performed by several short touches to the
switch rather than one long one. After each short touch allow about five
seconds for the hull to react.
• The trim tab hydraulic fluid reservoir is located in the aft machinery
compartment. The fluid level should be checked periodically and refilled
as necessary.
