Propeller Selection
For best all around performance from your outboard/boat
combination, select a propeller that allows the engine to operate
in the upper half of the recommended full throttle RPM range
with the boat normally loaded (refer to General Information ‑
Specifications). This RPM range allows for better acceleration
while maintaining maximum boat speed.

If changing conditions cause the RPM to drop below the
recommended range, such as warmer, more humid weather,
operation at higher elevations, increased boat load, or a dirty
boat bottom/gearcase, a propeller change or cleaning may be
required to maintain performance and ensure the outboards
durability.
Check full‑throttle RPM, using an accurate tachometer, with the
engine trimmed out to a balanced‑steering condition (steering
effort equal in both directions) without causing the propeller to
break loose.
