Monohull · 5 documented fitments
Propeller upgrade for the Oyster 62 — what fits, what changes.
Drawn from 5 documented Oyster 62 fitments: the common setup is a Varifold 4-blade behind the Perkins M185C. Typical result: 300–400 fewer RPM at cruise and up to 20% fuel saved over fixed pitch.

Worth knowing
Considerations for the Oyster 62
- 4 engine variants are documented for this model — repowers included. Sizing follows your engine and ratio, not the year in the brochure.
- Tip clearance rules the maximum diameter — roughly 10–15% of prop diameter to the hull. The Builder asks; we verify before supply.
Oyster 62 propeller questions
What size propeller does a Oyster 62 take?
Documented Oyster 62 installations most commonly run a Varifold 4-blade, matched to the Perkins M185C on a shaft drive. Exact size depends on your engine, gearbox ratio and aperture — every recommendation is verified by an engineer before supply.
How much fuel would a Oyster 62 save with an Autoprop?
Typical savings over a fixed-pitch propeller are up to 20% at cruise (documented band 15–30%, honestly less if you already run a folding or feathering prop). Put your engine hours and diesel price into the fuel calculator for your own numbers — then the Builder for a verified recommendation.
My Oyster 62 has a different engine than shown — does the data still help?
Yes. Repowers are common and the database usually holds several engine variants per model. The Builder starts from your actual engine and gearbox; the model records confirm diameters and clearances that are known to work on this hull.
