General
Description: It is an issue that Gori propellers installed on a SD20 saildrive will form grooves over time which will result in sea water penetration.
Notes
- Methods to deal with groves on the propeller shaft:
- Add/re-position spacers between the seals
- Machine propeller shaft and add a 316SS sleeve to return to original size
- Replace propeller shaft
- Periodic reposition the seals using shims (P/N 196315-02880 Circlip, Needle 52) allow longer life from the propeller shafts
- Propeller shaft diameter: 35mm (where the seals ride)
- Propeller shaft material: Likely 17-4 ph
- Unacceptable repair: Installing a Speedi Sleeve (99139 SKF for a 35.00mm/1.375") - the Speedi Sleeve is not rated for continuous salt water immersion
