Description
Davis Instruments Doel-Fin hydrofoil stabilizer — the original bolt-on hydrofoil for outboard motors and stern drives, typically rated 5-150 HP. Improves planing, reduces bow rise, and adds low-speed stability. Used take-off in good condition with Davis / Doel-Fin branding intact. Buyer must confirm fitment by part number, photos, dimensions, engine model, serial number, and application before purchase. Used marine part sold as-is unless otherwise stated. No returns on electrical, used, special-order, or installed parts.
