Marine Bow Thrusters

The water and the weather don’t always want to cooperate with your sailing plans — which is why you need good bow thrusters to navigate rivers and bays. These auxiliary boat thrusters are crucial for maneuverability, letting you move side to side as well as forward. When you’re surrounded by obstacles, facing heavy currents or feeling the wind pick up, the lateral movement from a marine bow thruster will be your saving grace.

Marine Parts Source will help boat owners and technicians find the right bow thruster for boats of any size. Get a bow thruster kit or replace individual parts and create a customized thruster layout with our large selection of parts and accessories. We sell the leading boat steering brands such as Vetus, Lewmar and Sleipner/Side Power that make marine thrusters.

Go Anywhere with Boat Side Thrusters

Hundreds of parts are in stock or available for bow thruster repairs and upgrades. Browse our large selection to find boat thruster propellers, motor assemblies, solenoid switches, joystick controllers, couplings, carbon brushes and more. We offer 12V and 24V bow thruster systems to match your power supply. If you’re looking for a specific part number, enter it into the search bar to find compatible replacements.

The knowledgeable staff at Marine Parts Source can assist anyone shopping for bow thruster parts. Call us toll-free at 866-388-0390 or use our contact form to get in touch. All in-stock marine thruster parts ship the same business day when you order by noon CT.
