where the rudder posts are) after putting the engines into idle and/or neutral, if
necessary. If you did "hole" the boat, go immediately to the "If an Emergency" on the
preceding pages.

If no hole, and still idling, is the boat vibrating? If "yes," put each engine into neutral
in turn, identify and shut down the offender. Then continue on one engine. Call
Anacortes Yacht Charters after you reach the closest safe harbor. If no vibration at idle,
slowly accelerate one engine at a time. Is there vibration on either? If "yes," run at idle
or on only the good engine, to reach a close, safe harbor. Then contact Anacortes Yacht
Charters. With a twin-screw boat, the damaged running gear can’t be used after hitting
an object. However, if while under way on one engine the other engine’s propeller shaft
rotates by itself because of water passing over it’s propellor, then you must let the
unused engine idle in neutral so that its transmission has lubrication, and the cutless
bearings on the damaged shaft are lubricated. This is still true whether the boat has
dripless shaft seals or a standard shaft “log”. When running on one engine with the
other idling as required, be sure that the idling engine is pumping water through its
exhaust pipe.

If there is no vibration on either engine, you probably did no running gear damage.
Congratulations! Our diver will check your vessel’s bottom upon your return, just as
after every charter.
