Propulsion System
3.6 Performance Issues & Propellers
It is extremely important that the boat is propped
to run at or very near the recommended top RPM
with an average load. If the top RPM is above or
below the recommend range, the propellers must
be changed to prevent loss of performance and
possible engine damage.
Your boat is equipped from the factory with
counter rotating engines that are mounted to
achieve quicker planing and optimum perfor-
mance. Therefore, the left hand rotation engine
is mounted on the port side of the transom and
the right hand rotation engine is mounted on the
starboard side. You should make sure that each
propeller matches the rotation of the engine.
Notice:
Before changing propellers to correct boat
performance problems, be sure factors such
as engine tuning, bottom and running gear
growth, etc. are not the source of perfor-
mance changes. Always be sure the load
conditions are those normally experienced,
before changing propellers.
Your boat was shipped with propellers that typi-
cally provide optimum performance for your boat.
However there are factors that can affect perfor
-
mance and propeller requirements.
The following are some other factors to con-
sider:
• You should be sure the load conditions are
those normally experienced. If the boat ran
in the required RPM range when it was new
and you have not added any additional gear
or heavy equipment and have not damaged
the propellers, there is a good chance the
propellers are not the problem.
• The addition of heavy equipment such as a
tower, life rafts, additional coolers, etc., will
cause additional load on the engines. Conse-
quently, different propellers may be required.
• Boats operated at high altitudes (above 2000
feet). Engines operated at high altitudes will
not be able to develop as much horsepower
as they do at or near sea level. Consequently,
different propellers may be required.
Notice:
Outboard engines can be damaged and the
warranty void if the boat is not propped
correctly. Always consult your Scout dealer
or authorized engine service dealer when
making changes to the propellers or if the
boat does not run near the top recommended
RPM’s.
