🔌 Function

The gasket and O-rings seal the stationary joints between saildrive housings, preventing gear-oil loss and seawater entry.

⚠️ Common Signs of Failure

• Gear oil or seawater leaks at a housing joint
• Saildrive housing has been separated
• Diaphragm service requires drive removal
• O-rings are flattened or cut
• Gasket is torn during disassembly

🛠️ Service Notes

• Use every ring the kit supplies and replace them all in one go; leaving one original ring in place is the usual reason a rebuilt unit leaks again
• Lay the kit out against the parts you remove so each ring goes to the right joint, as kits often contain rings of very similar size
• Clean each groove and seat and check it for scoring, corrosion and old sealant before the new ring goes in
• Ease each ring into place without stretching, twisting or dragging it over sharp edges or threads, and check it is seated squarely before closing the joint
• Add no sealant unless the workshop manual for your engine calls for it, and tighten the joints to the figures in that manual
