The key should fit tight without any side play, but it should not be so tight that it requires mechanical assistance to install it. Check the fit of the key into both the shaft and the propeller.The number one, most important thing, is to ensure that the propeller is properly fit to the propeller shaft taper.Ī poor fit can cause the propeller to come loose, or in the worst case, can cause the propeller shaft to break, resulting in the loss of the propeller.Inspect for defect, and check the shaft for straightness. Carefully clean the propeller bore, and the propeller shaft.

Side wear indicates that the propeller was loose on the shaft. Remove the key and inspect for damage.This is also a good time to inspect the taper contact.Īreas with good contact will appear clean, and areas with no contact will be dark or discolored. Once the propeller is removed from the shaft, carefully inspect the propeller bore and shaft for damage.It is recommended that you use a "soft gas" torch to slowly heat the entire hub evenly.Īvoid heating in one area or on one side of the hub as this can cause a buildup of stress in the propeller material. If the puller will not release the propeller, heating the propeller hub will expand it and release it from the taper.Ĭaution, improper use of heat can damage the propeller.Use caution to prevent damage to the propeller shaft and the propeller blades. Unseat the propeller from the shaft taper using a suitable puller.

Leave the nut on the shaft to prevent the propeller from falling off the shaft when it breaks free of the taper.

Loosen the thin nut and unthread it away from the propeller.

Once the propeller is firmly seated onto the taper it is often necessary to use a puller to remove the propeller.

This taper is 1:16, or 3/4" per foot, and is considered a self-holding taper. There are various types of propeller shaft tapers, but the SAE Marine Taper is the most common in North America.

Incorrect fit can cause vibrations and possible shaft failure.

It is critical that the propeller fits properly onto the taper.

The taper is what centers the propeller on the shaft.

The propeller shaft is machined with a taper at the propeller end of the shaft.
