BEFORE STARTING THE ENGINE
IMPORTANT: As an added precaution, the following steps must be observed before starting:
•
Do not start engine without water being supplied to seawater pickup pump (to prevent pump or en-
gine damage).

tor. If engine does not start, wait 1 minute to allow the starter motor to cool; then, repeat starting pro-
cedure.

perature. Refer to "Specifications - Crankcase Oil."
