Monohull · 5 documented fitments
Propeller upgrade for the Solaris 72 — what fits, what changes.
Drawn from 5 documented Solaris 72 fitments: the common setup is a Varifold 4-blade behind the Volvo Penta TAM D63. Typical result: 300–400 fewer RPM at cruise and up to 20% fuel saved over fixed pitch.

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 Solaris 72
- 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.
Solaris 72 propeller questions
What size propeller does a Solaris 72 take?
Documented Solaris 72 installations most commonly run a Varifold 4-blade, matched to the Volvo Penta TAM D63 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 Solaris 72 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 Solaris 72 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.
