Engine Compartment Blower - Chris-Craft 2015 21 Carina Owner's Manual

Engine Compartment Blower

Ventilate the engine compartment before starting the
engines. The compartment should be ventilated a
minimum of four (4) minutes.
The engine compartment may accumulate fumes when the
engines are not running. Before starting the engines ventilate
the engine compartment to remove any vapors that may have
accumulated. The best course of action is to open the engine
hatch and allow the vapors to escape. However, if that is not
possible, or is inconvenient, then each boat is equipped with
engine compartment exhaust blowers (2) which can be used
to ventilate the compartment. Run the blowers for at least four (4) minutes to ventilate the compartment
before starting the engines. If the boat is moving slowly, gasoline fumes can accumulate because not
enough air is moving through the engine compartment to keep it clear of vapors.
Anytime the boat is moving slow, engage the blower to remove any
fuel vapors that may be accumulating in the engine compartment.
Inspect the blower system prior to every use. The blower makes a distinctive sound when operating prop-
erly. If the blower is not operating, repair or replace prior to using the boat again. The blower switch is lo-
cated on the Helm Switch Panel.
