Monohull · 8 documented fitments
Propeller upgrade for the Hunter Horizon 26 — what fits, what changes.
Drawn from 8 documented Hunter Horizon 26 fitments: the common setup is a Varifold 2-blade behind the Yanmar 1GM10. Typical result: 300–400 fewer RPM at cruise and up to 20% fuel saved over fixed pitch.

Worth knowing
Considerations for the Hunter Horizon 26
- Shaft and saildrive variants exist across model years — the APS saildrive series covers the latter; check which yours is before comparing quotes.
- 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.
Hunter Horizon 26 propeller questions
What size propeller does a Hunter Horizon 26 take?
Documented Hunter Horizon 26 installations most commonly run a Varifold 2-blade, matched to the Yanmar 1GM10 on a shaft 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 Hunter Horizon 26?
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 Hunter Horizon 26 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 Hunter Horizon 26 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.
