01 / Overview

The strongest motor in the series: 80 lbs of thrust at 24 V, for boats up to 6.5 m. GPS anchor (±1 m) and heading hold work directly from the remote; full control via the Helmsman app.

The remote straps to your wrist or rod — hands stay free. The 24 V-scaled gauge protects batteries below 21 V, and an ON/OFF switch cuts power instantly.

The 10-step maximizer smoothly modulates prop speed and extends battery runtime up to 5× versus a classic gear switch — essential for trolling.

06 / FAQ

Which battery fits the Cayman 80BY GPS?+

The recommended battery is min. 100 Ah Gel / Li-ion 7S / LiFePO4 8S. For a precise runtime estimate at a given capacity, use the battery calculator.

Which fuse should I use?+

This motor draws up to ~45 A at full throttle, so the recommended fuse rating is 55 A (AGU-type or resettable) — in practice, round up to the nearest size available.

How do I choose the right shaft length for my boat?+

This model ships with a 152 cm (opcje 120/137/149) shaft. For the general sizing rule (transom or gunwale height → shaft length) see the sizing table on this page — Haswing motors also offer depth adjustment along the full shaft length, so a small mismatch is rarely a dealbreaker.

Does the motor run in salt water?+

Yes — the entire Haswing range runs in both fresh and salt water. After a season in salt water, rinse the shaft and prop with fresh water.

How do the GPS anchor and Helmsman app work?+

The GPS anchor holds the boat on a chosen spot to within about one metre regardless of wind and current, and heading hold keeps it tracking a set direction. The free Helmsman app (Android/iOS) adds route waypoints, track recording and a full-speed mode — the motor also runs entirely from the remote, no phone required.
