01 / Overview

A brushless motor with the factory digital maximizer, for boats up to 7 metres. The 100 cm stainless steel column is a sturdier build than the aluminium column in the 1.0/2.0S family, and resists corrosion in fresh and salt water.

The prop sits directly on the motor shaft; the 3-blade Ø 27.1 cm prop runs up to 1250 rpm underwater. The digital maximizer delivers smooth, stepless speed control and extends battery runtime up to five times versus a classic gear switch — essential for trolling.

The telescopic tiller adjusts over 35 cm and 180° of tilt, and folds down flat for transport. The universal transom bracket offers 7 mounting positions, for transom boards up to 68 mm thick. A 3-LED gauge calibrated to 12 V tracks the battery charge.

06 / FAQ

Which battery fits the Protruar 3.0S?+

The recommended battery is min. 130 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 ~75 A at full throttle, so the recommended fuse rating is 85 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 100 cm (stal nierdzewna) 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.
