Catamaran · 10 documented fitments
Propeller upgrade for the Fountaine Pajot Mahe 36 — what fits, what changes.
Drawn from 10 documented Fountaine Pajot Mahe 36 fitments: the common setup is an Autoprop H5 behind the Volvo Penta D1-20. Typical result: 300–400 fewer RPM at cruise and up to 20% fuel saved over fixed pitch.

Documented engine variants & what they wear
Aggregated from 10 real installations — not a size chart, a service record.

|---|---|---|---|---|---|---|
| Volvo Penta D1-20 | 19 hp / 3200 | Saildrive | 2.19:1 | Autoprop H5 | Left-hand | 8 |
| Volvo Penta D1-30 | 29 hp / 3200 | Saildrive | 2.19:1 | Autoprop H20 | Left-hand | 2 |
Indicative only — gearboxes and apertures vary between years and repowers, which is why every supplied propeller is verified against your boat first. Data current as of 2026.

Worth knowing
Considerations for the Fountaine Pajot Mahe 36
- Shaft and saildrive variants exist across model years — the APS saildrive series covers the latter; check which yours is before comparing quotes.
- Twin drivetrains are supplied as handed pairs (LH & RH) so both sides behave identically in close-quarters work — and any gain is doubled across two engines.
- 2 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.
Fountaine Pajot Mahe 36 propeller questions
What size propeller does a Fountaine Pajot Mahe 36 take?
Documented Fountaine Pajot Mahe 36 installations most commonly run an Autoprop H5, matched to the Volvo Penta D1-20 on a saildrive drive. Exact size depends on your engine, gearbox ratio and aperture — every recommendation is verified by an engineer before supply.
Will an Autoprop fit my saildrive Fountaine Pajot Mahe 36?
Yes — saildrive installations are documented for this model, using the APS saildrive variants with the appropriate spline and anodes. Tell us your drive model (e.g. Volvo 130S, Yanmar SD25) and we confirm the fitment.
How much fuel would a Fountaine Pajot Mahe 36 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 Fountaine Pajot Mahe 36 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.
