Outboard Stern Thrusters
The ST350-OB Stern Thruster from Sideshift is perfect for most
boats up to 60' in length; the unit mounts to the cavitation plate
of any outboard motor or sterndrive for easy in-water installation,
eliminating the mounting issues common to most outboard or
sterndrive powered boats. The unique mounting position creates zero
drag as the thruster rides above water when the boat is on plane.
Offering an immediate response with its powerful water cooled 24V
motor, the heavy-duty 8" aluminum propellers provide instant lateral
thrust for stress-free docking in any situation. Saltwater proven,
the thruster is anode protected and finished with anti-foul paint
over epoxy primer to prevent corrosion.
Shipped as a complete kit including
- Thruster
- Motor controller
- Wireless joystick
- Wiring harness and mounting hardware
- Outboard/Sterndrive mounting plate
- Fuse with digital voltage indicator
- Battery switch
- Wireless remote key fob
**Also available in white to match outboard color. Contact
factory to order.
Sideshift is proud to introduce the marine industry’s first
(Patent Pending) outboard mounted stern thruster! Finally, an
easy-to-install stern thruster solution that attaches directly to
any outboard or sterndrive powered boat from singles to multiple
engine setups.
Universal Mounting on any Outboard or Sterndrive
The new OB Series Stern
Thrusters from Sideshift are perfect for any boat up to 60′ in length. The
thruster mounts to the cavitation plate of any outboard motor or I/O for easy
in-water installation, and completely eliminates the mounting issues common to
most outboard or sterndrive powered boats. The unique mounting position creates
zero drag as the unit rides above water when the boat is on plane. The extreme
aft location of the thruster provides a strong pivot point advantage for
immediate response in stressful docking situations. When seconds count,
Sideshift delivers the performance you need.
No bulky tunnel is required, and our unique universal mounting system
requires no holes below the waterline, eliminating the risk of
leaks associated with all other types of thruster systems. And
when combined with your Sideshift or factory bow thruster, you can add
our dual wireless joystick option for easy single-handed operation of both
thrusters for true 360 degree control of your boat in any situation.
Did you know that according to BoatUS Insurance, a full 44% of
sinkings are a result of failed fittings below the waterline?
Silent and immediate response is provided by our prop-in-water design, 8”
aluminum propellers, and heavy-duty water cooled motor. Saltwater proven, our
rugged OB Series Stern Thrusters are anti-foul painted and anode-protected to
prevent corrosion.
Maneuver with confidence into the tightest slips with a simple touch of the
wireless joystick. Step onto the dock while maintaining total control of your
boat with our wireless key fob controller.
Shipped as a complete kit with thruster, controller, mounting hardware,
wireless joystick, fuse, digital voltage indicator and battery switch,
installation takes less than a day.

Installation
Sideshift bow and stern thrusters can be installed in less than a day.
Conventional thrusters take days to install by a professional. At Sideshift, we
make installing your thruster a breeze.
- Easy, do-it-yourself installation
- Detailed installation manual, installation videos, and unlimited phone
support
- Can be installed with your boat in the water
- No holes drilled below the waterline
- No motor inside the hull
- Can be installed by any marina or boatyard
Sideshift bow and stern thrusters are a great DIY project, or can be
installed by any marine service department or boatyard. No previous
experience or special tools are required. In fact, while other types of
thrusters can take days to install and should only be done by a professional,
our revolutionary design will normally take you only hours to complete,
saving you thousands of dollars in installation costs. And your boat
can often be back on the water the same day!
The Sideshift thruster kit provides all the necessary components and
installation hardware, including the thruster, mounting bracket, wiring harness
and cable, motor control unit, wireless joystick (no wire run to the helm!) and
remote control key fob, fuse with digital voltage indicator, and battery
switch. The boat owner only has to add a power source, and a small amount of
cable to connect the batteries. Everything else you need is in the kit.
Installing a Sideshift bow and stern thruster is so easy that you can do it
yourself in less than a day. Other thruster systems can cost thousands of
dollars to install and take up to a week to complete. Not Sideshift! Just follow
the on-line video and easy, step-by-step instructions that are included with
every kit to get your boat out on the water faster. And we’re always available
to provide phone support if any questions come up.
Local Installers
Or, if you aren’t comfortable installing a Sideshift thruster yourself, you
can take it to your local marina or boatyard to let the professionals handle it.
Unlike tunnel thrusters which can cost thousands of dollars to install,
Sideshift thrusters can be installed for as little as $800-$1,200. Our thrusters
have been specifically designed for easy installation by any marine mechanic,
and as always, we’re available to speak with your installer if there are any
questions.
2-YEAR WARRANTY
