Autoprop

Bearing caps for the autoprop.

These are replacement caps for my APS H5 autoprops, but they will probably fit some other models as well.

I once lost a blade, and together with the blade the bearing cap. It was bad enough I had to order new blades, and I didn't want to order a new bearing cap as well.

The advantages of my design:

• The bearing caps are much lighter than the metal ones. This increases the service life of the bearings and saildrive.
• A special tool is no longer needed, a regular socket or spanner #32 will fit on them.
• No more tool holes that get clogged up with marine growth.
• Less metal, so less consumption of the expensive annodes.
• You can just print new ones if they get damaged or lost.
• You could print each cap with a different color so it is easier to identify the individual blades.

The standard O-rings and grease plugs will fit on these caps.

Notes

• I used PETG for printing them, as PETG is oil and water resistant.
• My sure to dry the filament properly or it will cause leaks.
• Due to the design, use of a support interface layer filament is necessary.
