01 / Overview

The Comax N55 is one of the most advanced models in the Haswing range. Its key feature is an electronically adjustable shaft — UP/DOWN buttons change its height across a 265 mm range, so the motor fits most boats and dinghies without manual mechanical adjustment.

The 2:1 steering system means a 45° tiller movement turns the boat 90° — far easier to manoeuvre than a classic 1:1 ratio. The 8-step maximizer smoothly modulates prop speed, saving battery and extending runtime up to 5× — ideal for trolling.

A 3-LED gauge scaled to 12 V shows battery state. The tiller folds and adjusts across 120°, with a safety key included in the kit. The universal transom bracket, resistant to heat deformation, offers 10 tilt angles and mounts on transoms up to 65 mm thick. The 3-blade Ø 23.6cm prop delivers high torque at 1250 rpm. Runs in fresh and salt water.

How do I pick the right shaft length?+

Transom / gunwale height	Mount	Recommended shaft length
30–40 cm	transom	54–67 cm
40–50 cm	transom	80 cm
50–60 cm	transom	90–100 cm

80–100 cm	bow	149–152 cm

Haswing motors offer depth adjustment along the full shaft length, so the figures above are a starting point, not a strict rule. When in doubt, the importer can advise on the best fit.

06 / FAQ

Which battery fits the Comax N55?+

The recommended battery is 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 61–89 cm (elektronicznie regulowana) 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.
