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 through the outboard vertical drivesha
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 engine. e cool water absorbs heat produced
by the engine, before being emitted via the coolant exhaust system.
ere 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 water pump and impeller should be inspected for
debris, damage or excessive wear due to water chemistry such as
mineral or silt conditions. Damaged parts will a ect 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 cooling systems.
