D. BILGE BLOWER

To prevent buildup of gasoline fumes to the explosive

level in the engine compartment, the bilge blower

must be run for at least four (4) minutes before

starting the engine and kept running at all times

when the engine is running to ensure that there

will be adequate ventilation when you are moving

slowly.

EXPLOSION/FIRE HAZARD – Run blower at least

four (4) minutes before starting engine or gen er a tor.

Check bilge and engine com part ment for fumes.

! WARNING

Do not allow obstructions to interfere with bilge blower

or ventilation intake operation. Engine performance

may be adversely affected.

! WARNING

BILGE BLOWER

(FIG. 4.2.1)

The bilge blower is protected by a breaker on the

aft EIM located on the bilge component board (see

Fig. 6.5.2).

If the liquid level in the bilge is higher than

normal and the bilge pump empties the bilge

when you use the ON switch, either the breaker

for the automatic bilge pump circuit has blown

or the ﬂ oat switch is not operating properly.

Have it checked immediately. If the ON switch

does not operate the pump, DO NOT use the

boat until the problem is corrected.

The bilge pump automatic circuit is protected by

a breaker on the main DC breaker panel located

under port seat aft cushion (see Fig. 6.7.1). The

bilge pump manual circuit is protected by a breaker

on the aft EIM located on the bilge component board

(see Fig. 6.5.2).

1. MAINTENANCE

Frequently inspect the area under the ﬂ oat switch

to ensure it is free from debris and gummy bilge

oil. To clean, soak in heavy duty bilge cleaner

for 10 minutes, agitating several times. Check

for unrestricted operation of the ﬂ oat. Repeat the

cleaning procedure if necessary.

Inspect the bilge pump intake and keep it free

of dirt or material which may impede the ﬂ ow

of water through the pump. To clean the pump

strainer, depress the lock tabs on both sides of the

pump and lift the pump motor.

TROUBLESHOOTING:

If water does not come out of discharge hose:

1. Check the “BILGE PUMP” breaker on main DC

Breaker Panel (see Fig. 6.7.1) to ensure it has

not been tripped.

2. Remove the motor module to see if the impeller

rotates with the power on.

3. Remove any debris that may have accumulated

in the nozzle section or strainer base.

4. Check hose and connection on hull side for

debris and proper connections.
