Engine Checklist Before Each Outing
Every engine option may require different checks
before each use, but a general engine checklist is
included here as a guide.
• Check crankcase engine and gear case oil
levels.
• Check steering fluid.
• Check power trim fluid.
At Helm/ Deck
• Check power trim for operation.
• Check control lever for operational defects.
Check the clip and safety lanyard for
functionality.
• Check gauges for accuracy.
• Check fuel level and ensure the level is sufficient
for the trip with a reserve.
Engine Cooling System
Your typical engine normally utilizes a raw water
system for cooling the engine with intakes at the
gear case. It is important that this system continues
to run unobstructed at all times to avoid hazardous
situations and to ensure a safe voyage.
Raw water is drawn up into the outboard vertical
drive shaft housing through pick-up feeds in the
gear case vicinity.
Water passes through a power head thermostat
which controls how much water circulates through
the power head. The cool water absorbs heat
produced by the engine, before being emitted via
the coolant exhaust system.
There is a access hole on the port side of the power
head which shows a visual stream of water at all
times. If no water is visible with the engine running
shut down the engine and investigate the problem.
At times this relief hole can be plugged by debris.
Impeller/ Water Pump
Periodically, the coolant system’s impeller and water
pump should be inspected for debris, damage or
excessive wear due to use, water chemistry such
as mineral and/or silt conditions. Damaged parts
will affect the system’s ability to function, and may
cause engine overheating or damage. Contact
your closest Regal dealer for more information and
maintenance schedules of key outboard engine
systems.
Thermostat
If the temperature gauge starts yielding abnormal
readings, it may become necessary to look at
or replace the power head thermostat after
determining whether it is functioning properly.
The thermostat reads the temperature of coolant
and determines whether to open or close a valve
to allow warm sea water to pass into the exhaust
manifold. The thermostat may recirculate hot
coolant for the purposes of reaching standard
operating temperatures.
