GENERAL INFORMATION
Propeller Selection
Select a propeller that allows the engine to operate at the recom-
mended full throttle RPM range with the boat normally loaded (refer
to Specifications). This RPM range allows for better acceleration
while maintaining maximum boat speed.
If changing conditions (such as warmer, more humid weather, opera-
tion at higher elevations, increased boat load, or a dirty boat bottom/
gear case) cause the RPM to drop below the recommended range
a propeller change or boat cleaning may be required.
Check full-throttle RPM using an accurate tachometer with the en-
gine trimmed out to a balanced-steering condition (steering effort
equal in both directions) without causing the propeller to “break
loose.”
