To provide reliable & safe thruster installations in more boats, we offer modified versions of our DC electric thrusters in watertight housings for use in stern & other locations that may get wet or be exposed to petrol fumes. These thrusters are fully ignition protected (ISO 8846) for use in boats with petrol engines. They have a hermetically sealed composite housing around all electric parts. This provides the ignition protection as no petrol fumes can enter & be ignited by sparks. The other advantage is that the electric parts that could be damaged by water are also covered & protected, making these thrusters the ideal choice for other stern thruster installations where it is difficult to ensure that the thruster will always remain dry.
