Boat Systems

Section 4

General Description

This section contains general theory and functional

information about the boat systems. This information

is intended to give you an idea about how each boat

system is configured and how it should be used.

The content of this section is based on the most cur-

rent design and assembly information available at the

time of publication. The information and illustrations

are general representations of the boat systems, the

information is not meant to be used as a detailed parts

manual or a service manual.

Certain features, parts, systems, and accessories dis-

cussed in this section might not be found on your boat.

This boat and these boat systems should be main-

tained by an experienced marine technician.

Specific troubleshooting and parts information for each

accessory component might be included in the OEM

literature contained in your owner’s bag.
