The skin fitting is recommended. It must be oriented
to the bow of the boat.
In case of high speed vessel (over 15 knot) it is
advised to make some holes on the backside of the
shape, in order to reduce dynamic prevalence during
navigation.
Pre-existing
As alternative, it is possible Tee into a pre-existent
seacock
water inlet as long as the following conditions are
adapting
met:
(alternatively)
INSTALLATION NOTES
•
Allow a minimum 3/4" on-off ball valve on the water intake.
