Maintenance & replacement
- Replacement guide — the wear signs, the shaft-wiggle test, what the job costs, and how to order the right replacement.
- Skeg bearings — sizing the cutlass bearing in a skeg, strut or P-bracket.
- Marine shaft bearings explained — the full propeller-shaft support system from gearbox to prop, and which bearing does what.
- Cutlass vs Cutless — two spellings, one part: the trademark story and how to cross-reference sizes between brands.
