6.1.4 Struts
Each propeller shaft is supported by manganese bronze
struts fastened to the bottom of the hull. The struts have
replaceable bearings to minimize wear and to protect
the shaft at the points where it passes through the strut
hubs. The strut bearings should be inspected annually
and replaced as necessary. Location of the struts can be
found in the Underwater Gear Components illustrations
at the end of this chapter.
6.1.5 Shaft Log / Stuffing Box
The shaft log is a fiberglass tube inserted into an open-
ing in the bottom of the boat aft, for the propeller shaft.
A short length of flexible hose connects the shaft stuffing
box to the shaft log. See fig. 6.1.
The stuffing box keeps water from leaking around the
shaft into the boat. The stuffing box has a Flex packing
system.
The shaft seal assemblies should be inspected at least
annually
.
6.1.6 Alignment
Aligning the engine with the propeller shaft is critical for
smooth operation of your boat. Shaft alignment may
change slightly after your boat is in use. Your dealer
should check alignment as part of commissioning, par-
ticularly if there is vibration, a drumming sound, or loss
of RPM’s.
If alignment is necessary, see your authorized service
technician.
6.2 Steering Components
Keep clear of moving steering parts at all times. Pro-
tect moving parts from access during normal use!
6.2.1 Steering System
Figure 6.4
The steering system on your boat uses a rack and pinion
setup that connect the wheel to the steering gear via a
direct drag link. Fig. 6.4 gives you a view at some of the
basic components of this system.
To keep it in the top operating condition please read your
manual supplied in your owner’s packet. This manual con-
tains all the system requirements and maintenance require-
ments to keep your steering system working for years.
