Monohull · 5 documented fitments

Propeller upgrade for the Jeanneau SO 52.2 — what fits, what changes.

Drawn from 5 documented Jeanneau SO 52.2 fitments: the common setup is an Autoprop H6 behind the Yanmar 4JH3HTE. Typical result: 300–400 fewer RPM at cruise and up to 20% fuel saved over fixed pitch.

Considerations for the Jeanneau SO 52.2

  • 5 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.

Jeanneau SO 52.2 propeller questions

What size propeller does a Jeanneau SO 52.2 take?

Documented Jeanneau SO 52.2 installations most commonly run an Autoprop H6, matched to the Yanmar 4JH3HTE 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 Jeanneau SO 52.2 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 Jeanneau SO 52.2 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.
