E - 5 ENGINE COOLING SYSTEMS
A. Raw Water Cooling
For twin engine installations, always check
drive shaft rotation before propeller installation.
A right hand rotation propeller must be
installed on the starboard propeller shaft.
Similarly, a left hand prop must be installed
on the port propeller shaft.

system..This.cooling.system.is.a.seawater.system..

See.Figure.E-3.
Never operate your engine without a
thermostat. Engine damage can occur and is
considered operator negligence and therefore
not covered under the engine warranty.
Figure E-3: Prop Installation
If engine should overheat, turn off engine,
look for obstructions to water pick-up. If any
obstructions are found, clear the obstructions
and run engine again at 00 RPM in neutral
and check temperature gauge to verify
condition. If overheating still occurs, return to
port at low RPM to prevent excessive over-
heating and engine damage. Consult with
your certified engine dealer for service.
NOTICE
Should it be necessary to change propellers,
always use an appropriate propeller removal
tool or “Prop Puller.” DO NOT attempt removal
using a hammer. Damage to the propeller or
propeller shaft can result.
