5. Pull the propeller straight off the shaft. If the propeller is seized to the

shaft and cannot be removed, have the propeller removed by an

authorized dealer.

IMPORTANT: To prevent the propeller hub from corroding and seizing to the

propeller shaft (especially in saltwater), always apply a coat of the

recommended lubricant to the entire propeller shaft at the recommended

maintenance intervals and also each time the propeller is removed.

6. Coat the propeller shaft with Extreme Grease or 2‑4‑C with PTFE.
