Propeller Selection
It is the responsibility of the boat manufacturer and/or the selling dealer to equip the power
package with the correct propeller. Refer to
Everything You Need To Know About
Propellers
(90-8614492) .
Select a propeller that will allow the engine power package to operate at or near the top end
of the recommended WOT operating rpm range with a normal load.
If full throttle operation is below the recommended range, the propeller must be changed
to prevent loss of performance and possible engine damage. On the other hand, operating
an engine above the recommended operating rpm range will cause higher than normal wear
and/or damage.
After initial propeller selection, the following common problems may require that the
propeller be changed to a lower pitch.
• Warmer weather and greater humidity cause a loss of rpm.
• Operating in a higher elevation causes a loss of rpm.
• Operating with a dirty boat bottom causes a loss of rpm.
• Operating with increased load (additional passengers, pulling skiers) causes a loss
of rpm.
For better acceleration, such as is needed for water skiing, use the next lower pitch
propeller. Do not operate at full throttle when using the lower pitch propeller, but not pulling
skiers.
