Bolt on Bow thrusters are mounted in pairs, one on each side of the boat approximately even with the drivers position on each side of the boat. The thrusters are mounted far enough aft and do not extend below the bottom of the boat so as not to interfere with beaching in most cases as you can see in our video operating while beached.

You will find plenty of uses for the remote thruster control that works anywhere on the boat and up to 600 feet away.

Clutch operated hydraulic system

HydraNautics thrusters are powered by our clutched belt drive system mounted on the generator. Our system only draws power from the generator when you push on a joystick to manuever and disengages instantly when you release the joystick. Direct drive pumps used by our competitors hydraulic systems run all the time the generator is running wasting power. A few of the advantages of Hydranautics besides being the most powerful are:
  • Only operates when you push joystick
  • No continuous whining noise
  • No water coolers to cool hot oil from continuos running pumps that run anytime generator runs.
  • Uses less fuel
  • More KW of electricity available instead of wasted
  • Never harmed a generator or warranty in over 30 yrs and thousands of boats, others have!
