I have a Hunter 380. I bought and installed an Exturn 24 volt external bow thruster. No speed loss. Plenty of power to spin the boat as needed for docking. I purchased the thruster from Germany and did my own install. You should have an open V shaped area in the bow forward of the water tank. The two 12 volt batteries and disconnect switch are up in the bow area also. I mounted the joystick on the pedestal.
