01 / Overview
The same feature set as the Osapian 30 — silver-contact gear switch, 5-LED battery gauge, telescoping tiller and universal transom bracket — stepped up to 40 lbs of thrust and 500 W. The 2-blade Ø23 cm prop turns with more torque than the 30: up to 1380 rpm.
A 5-forward/3-reverse gear switch with silver-plated contacts keeps the motor running reliably for years.
The telescoping tiller (21–35 cm) tilts through 110° of travel: 20° up, 90° down for transport.
The universal transom bracket offers 10 positions, adjusts along the full shaft length, and fits transoms up to 68 mm thick.

07 / FAQ
Which battery fits the Osapian 40?+
The recommended battery is Min. 80 Ah Gel, Li-ion, LiFePO4. For a precise runtime estimate at a given capacity, use the battery calculator.
Which fuse should I use?+
This motor draws up to ~40 A at full throttle, so the recommended fuse rating is 50 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 80 cm, Ø28 mm 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.
