Checking propeller

EWM00321

WARNING

You could be seriously injured if the engine accidentally starts when you are near the propeller.

●Before inspecting, removing, or install- ing the propeller, remove the spark plug caps from the spark plugs. Also, place the shift control in neutral, turn the main switch to “” (off) and re- move the key, and remove the lanyard from the engine stop switch. Turn off the battery cut-off switch if your boat has one.

●Do not use your hand to hold the pro- peller when loosening or tightening the propeller nut. Put a wood block be- tween the anti-cavitation plate and the propeller to prevent the propeller from turning.

Checkpoints

●Check each of the propeller blades for wear, erosion from cavitation or ventila- tion, or other damage.

●Check the propeller shaft for damage.

●Check the splines / shear pin for wear or damage.

●Check for fish line tangled around the pro- peller shaft.

●Check the propeller shaft oil seal for dam- age.

NOTE:

If the shear pin equipped: it is designed to break if the propeller hits a hard underwater obstacle to help protect the propeller and drive mechanism. The propeller will then spin freely on the shaft. If this happens, the shear pin must be replaced.
