4. The transom, under the swim board, slightly
starboard.
5. The T-handle in the center bilge
compartment, located beneath the
piehole near the driver’s helm.
6. This circulating hose on the starboard side and
aft of the engine under the heat exchanger may
or may not have a plug. If equipped with a plug
simply remove it. If not follow the below steps.
Loosen the clamps holding the hose in place
and allow it to drop down to drain any residual
water in the system. (This is the lowest area of
the circulating water system, and gravity should
allow any water to drain that was not previously
drained.)
NOTE : When reconnecting this hose as the
boat is recommissioned prior to operation, be sure to tighten the clamps holding this hose—but
DO NOT
OVERTIGHTEN.
The clamps should be tight enough to prevent leaking, but over-tightening them will accelerate
wear-and-tear on the hose and could eventually cause failure that is not covered under warranty.
All drain plugs in the boat, regardless of the engine manufacturer, must be
removed and all water drained prior to storage, particularly during winter
months, to avoid potential freezing and damage to the engine and the boat.
Such damage is not covered under warranty!
