01 / Overview

The “Y” variant of the GPS line with a redesigned remote (code 50813, 3×AAA) featuring a large, legible display. GPS anchor, cruise control, track recording and heading control — all directly from the remote, no phone needed.

The Helmsman app remains available as a companion: steering, throttle and position with GPS accuracy down to one metre.

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 55BY GPS?+

The recommended battery is min. 100 Ah Gel / Li-ion 3S / LiFePO4 4S. For a precise runtime estimate at a given capacity, use the battery calculator.

Which fuse should I use?+

This motor draws up to ~50 A at full throttle, so the recommended fuse rating is 60 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 137 cm (opcje 120/149/152) 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.
