The SS340 Bow Thruster from Sideshift is perfect for boats up to 40' in length; the unit mounts on the exterior of a V-shaped bow. This creates a forward pivot point that gives the boater optimum control. No expensive tunnel in the hull is required and all mounting holes are above the waterline. Offering an immediate response with its powerful water cooled 12V motor, the heavy-duty 8" aluminum propellers quickly pull the boat quietly and smoothly. Saltwater proven, the rugged aluminum and stainless steel bow thruster is anode protected to prevent corrosion. It is finished with anti-fouling paint over epoxy primer. 23.5" W x 27.5 " L. 33lbs.
