01 / Overview

The stronger variant in the G line: 130 lbs of thrust at 1800 W / 24 V, a 100 cm stainless steel column (sturdier than the aluminium column on the 3.0G), for boats up to 7.5 metres. Drive is transmitted through the same planetary gearbox as the 3.0G.

The digital maximizer offers 8-step speed control and extends battery runtime up to five times versus a classic gear switch. A 5-LED gauge calibrated to 24 V tracks the battery charge.

A keyed safety lanyard, clipped to a life vest or wrist, cuts the motor instantly when pulled. The 3-blade Ø 30 cm prop (1100 rpm) carries a fin guarding against bottom strikes.

The tiller adjusts over 100° of tilt and folds down for transport. The metal transom bracket resists rust and heat deformation, offers 7 mounting positions, and can be padlocked between the transom clamps against theft.

06 / FAQ

Which battery fits the Protruar 4.0G?+

The recommended battery is min. 130 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 ~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.
