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.
