EXTURN Installation

Adaptor Installation Installation of an EXTURN thruster is quick and easy. Simply drill a 50 mm diameter hole through the hull for the S/S through-hull fitting (attached to the thruster) which also feeds the required wiring. This through hull fitting is supplied with a watertight seal which eliminates the need of additional GRP work. Also supplied as part of the installation kit are S/S fixings to be bolted through two 18 mm pre drilled holes. This also includes watertight seals and provides ultimate security and rigidity of your EXTURN thruster installation. EXTURN installation (video)
