precision meets power

The Ultra Marine Brushless motor series is handmade and of the highest material quality.

Originally, these high performance motors come from the copter range. Their excellent performance and torque characteristics with low power consumption make them almost ideal for the marine industry. Due to the outer rotor design, the engine can draw a lot of cooling air. This eliminates a complicated water cooling. The motors are double-ball bearing with ground steel shafts of 4 mm diameter and available in two different lengths. Due to the 16 mm and 19 mm mounting pitch circle, it can be mounted on most motor mounts and thus replace brush motors. Due to the compact design and the low weight you will find space in the smallest boats. Whether as a ship propeller with propeller or as a jet propulsion: With the Ultra Marine engines you are technically up to date!
