Stern drain plug checks
Loosen the stern drain plugs and remove
them, and then make sure that the plugs and
O-rings on the plugs are not damaged and
that there is no foreign material on the
threads or O-rings on the plugs. NOTICE:
Before installing the stern drain plugs,
clean the drain plug threads and the O-
rings on the plugs to remove any foreign
materials, such as dirt or sand. Otherwise,
the stern drain plugs could be damaged,
allowing water to enter the engine com-
partment. Check the O-rings on the stern
drain plugs and make sure that the plugs
are tightened securely before launching
the watercraft. Otherwise, water may
flood the engine compartment and cause
the watercraft to submerge.
