Rudder Stuffing Gland; Trim Tabs; Bilge; Bilge Pumps - Maxum 3700 SCR Supplemental 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.
PRODUCT DAMAGE HAZARD! 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 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 ring are at the bottom in the sleeve.
7. Tighten the packing gland nuts until resistance is felt.

LOSS OF CONTROL HAZARD!
• Improper use of trim tabs may cause loss of control!
• Do not use trim tabs in a following sea as they may cause broaching or other unsafe
handling characteristics.
• Never allow anyone unfamiliar with trim tabs to operate them and do not use trim tabs
to compensate for excessive unequal weight distribution.

Bilge

Bilge Pumps

Your yacht is equipped with three automatic impeller-type bilge pumps which are used to pump water out of the
bilge. Bilge pumps are controlled by automatic bilge pump float switches (autofloat switches) and/or switches at the
helm. Bilge pumps are wired directly to the battery so they will normally function even when the yacht is completely
shut down and unattended.
! CAUTION!
Trim tabs control the longitudinal and lateral trim
of your boat at cruising speeds and are controlled
by two rocker switches at the helm station.
Before using the trim tab rocker switches, we
strongly urge you to read and understand the trim
tab operation manual included in your yacht's
owner's packet and observe the following:
• Once the best bow cruising trim is reached, use
the port or starboard trim switches, one at a time,
to correct unequal lateral loading.
• 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/pump is
located in the engine compartment. The fluid
level should be checked periodically (at least
once a year) and refilled as necessary.
