make. The type, size, and design of your pro-
peller have a direct impact on acceleration,
top speed, fuel economy, and even engine
life. Yamaha designs and manufactures pro-
pellers for every Yamaha outboard motor and
every application.
Your Yamaha dealer can help you select the
right propeller for your boating needs. Select
a propeller that will allow the engine to reach
the middle or upper half of the operating
range at full throttle with the maximum boat-
load. Generally, select a larger pitch propeller
for a smaller operating load and a smaller
pitch propeller for a heavier load. If you carry
loads that vary widely, select the propeller
that lets the engine run in the proper range for
your maximum load but remember that you
may need to reduce your throttle setting to
stay within the recommended engine speed
range when carrying lighter loads.
VF150LA, VF175LA:
Yamaha recommends "Ventless Design For
new 4-stroke VMAX SHO" for your propeller.
For further information, consult your Yamaha
dealer.
VF150XA:
Yamaha recommends to use a propeller suit-
able for the "Shift Dampener System (SDS)".
For further information, consult your Yamaha
dealer.
To check the propeller, see page 86.
