9.7.4 Assembly procedure
When bilge is being used, assemble in accordance
with the following.
(1) Assembling the bilge pump
• Select a dry place above the bilge water
level.
• Select the location for the bilge pump taking
into consideration the length of the switch
cable (approx. 3 m) and its attachment point,
and the position of the battery.
• Position at a 45° angle as shown in the
illustration with the nozzle facing up, and 50-
70 cm from the bottom of the boat.
(2) Assembling the switch
• Attach in a place to insure easy operation
away from rainwater.
• Connect the terminal to the battery.
(When the cord will not reach the battery, an
extension of no greater than 3 m length
suitable for AV3mm
2
can be attached.)
(3) Positioning the strainer
• Attach at the place where the greatest
amount of water is collected when the boat is
stopped.
• It is best to place the strainer as close to the
bilge pump as possible. Cut the 3 m hose to
a length of 1.2 m-1.8 m and attach allowing
plenty of give.
• Check the strainer during a test operation
before screwing firmly into place.
(When the strainer is screwed in, be
especially careful not to damage the bottom
of the boat.)
• The strainer contains a weight, and can be
used with the weight in place.
• Always keep the strainer clean.
