2011 Four Winns V335 Boat Owners Manual

Under your normal load conditions, the engines
should turn within the maximum RPM range when at
full throttle. If the engines exceed the recommended
RPM, an increase in pitch or diameter is required.
If the engine RPM is too low, a decrease in pitch or
diameter is required.
Always check shaft rotation before propeller installa-
tion. A right hand rotation propeller must be installed
on the prop shaft connected to a starboard engine.
Similarly, a left hand prop must be connected to the
port engine shaft. The propellers must rotate outboard
not inboard.
The load carried in a boat will directly affect perfor-
mance of the engine. If an engine that is not develop-
ing full power, be sure the engine is properly tuned
and load conditions are those normally experienced,
before changing propellers.
Be sure the propellers are of the correct blade
configuration, diame ter, pitch, and shaft size to assure
good performance. For additional information on
factors affecting performance and/or assistance with
your selection, please consult your Four Winns dealer.
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.
Certain stern drive engines utilize a raw water cooling
system. This cooling system is a seawater system.
Seawater (raw) water is taken in through water inlets
on the both sides of the lower gear unit of the stern
drives models. Water pumped to the engine by the
seawater pump is circulated through the engine by the
engine circulating pump. A thermostat controls the
engine operating temperature by determining the
amount of water to be taken in, recirculated and
discharged. The water is discharged through an idle
exhaust relief and the exhaust through the propeller
hub. A temperature gauge(s) located on your instru-
ment panel monitors engine(s) temperatures.
For shipping reasons, the propellers are not factory
installed. Initial installation of the propellers will be
performed by the dealer during pre-delivery service.
See Figure E3.
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 E3: 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 1500 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.
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.
