Accelerated marine growth occurs when operated in salt water. This makes
it critical to flush the cooling system with fresh water after each use. This
fresh water flushing can be done with the boat either in or out of the water.
Instructions for accomplishing this are provided in Section 5, After Each
Use.
ELECTRICAL SYSTEM
The electrical system on your Ilmor High-Performance Marine engine is a
12-volt negative ground system. As a result, it is important to keep in mind
that operators must avoid reverse polarity, which could lead to extensive
damage of the electronics. Any damage occurring as a result of reverse
polarity will not be covered by warranty.
Reversed polarity also presents a serious shock risk. Turning off a breaker
appears to remove power from the circuit because it turns off whatever is
connected to that circuit. But with reversed polarity you have disconnected
from ground, not from power. The circuit is live.
WARNING!
Always connect the positive (+) battery cable first.
The
battery positive cable (+) connects at the starter motor battery post.
The positive post of the battery is connected to the large post provided
on the starter motor with marine grade single ought (1/0) starter wire
and appropriate eyelet. After the connection is made, all other positive
engine circuits will be connected to the battery positive from this junction.
The supplied heavy rubber boot (red) must be used on the starter motor
terminal to shield the terminal and prevent accidental contact.
WARNING!
Always disconnect the negative battery cable (-) first before
disconnecting the positive battery cable (+).
The battery negative (−), or
ground, connects to the stud at the engine bell-housing.
WARNING!
Never use jumper cables and a booster battery to start your
engine.
WARNING!
Never recharge your battery in the boat.
