DC Electrical System
Your boat is equipped with a 12-volt DC (Direct Current) electrical system.
This is a comprehensive system that is designed to meet your present and
future 12-volt electrical needs. Wire-runs and connections are positioned to
prevent abrasion and exposure to moisture, as well as to remain
accessible for inspection, repairs, and the addition of aftermarket
electrical accessories.
Wires used throughout the DC electrical system are plastic coated and
color-coded. Connections are made using crimped connector points. The
electrical system is virtually maintenance free, with only the batteries
requiring periodic inspection and maintenance.
Batteries
The DC electrical system is divided into three areas, each powered by one
or more 12-volt batteries:
• Engine Batteries - one for each engine
• Accessory Batteries - two each 12-volt batteries parallel connected to
produce 12-volts
• Generator Battery - one 12-volt
The battery bank is located on the port side of the engine room.
Access to the batteries is accomplished by removing the Battery Box
cover. For boats equipped with a Passerelle, batteries are between
the engines under a floor plate.
Engine Batteries
Each propulsion engine has its own battery.
Electricity from each battery to its engine is controlled by a master
disconnect switch. These switches are located in the engine room near the
base on the aft bulkhead. To provide electricity to the engines, turn the
master disconnect switches to the ON position. (Port switch shown)

Note:
When an optional Passerelle is installed, the batteries are
moved to beneath the floor plate between the engines. The
Passerelle hydraulic unit is placed where the batteries are
shown in these photos.
