The new Proportional thrusters from Lewmar have unlimited run-time, are very quiet in use, maintenance free and suitable for 24V installation The proportional series can be controlled by one of the four new proportional control panels developed for this new type of motor.

The proportional thrusters motor is a nearly silent motor and has unlimited runtime. The induction motor is controlled by the Lewmar Curtis controller. This in-house engineered motor controller can control 24V inputs. With this new system, Brushless motors have been chosen for their efficiency and unlimited runtime, and their ability to withstand tough sailing.

Retrofitting the Lewmar proportional series is also very easy. The proportional thrusters are backwards compatible to replace existing Lewmar bow thrusters installations.
