INSTALLATION INSTRUCTIONS
– STERN THRUSTER
Stern thrusters can be installed with the boat in water or on land, although land-
based installation is more convenient for transom, swim platform and sterndrive
mounting. Outboard/Outdrive mounting can be done easily with the boat in the
water.
View installation procedures on-line at Installation - Sideshift Bow Thrusters and
Stern Thrusters.
Stern Placement for Transom or Swim
Platform Mount(For outboard/sterndrive
mount skip to page 34. For wakeboat
mount skip to page 39.)
There are three guidelines you must follow to successfully mount the stern thruster
on the transom or under the swim platform on inboard-powered boats:
1. The top of the thruster propellers must be a minimum of 5 inches (12 cm)
below the waterline.
2. The area across the back of the boat must be clear to allow adequate side to
side flow for the thrusters to be effective. For example, a thruster cannot be
installed between two outdrive motors, otherwise the water forced to the side
by the thruster propellers will be blocked by the motors and side thrust will be
negligible.
3. The thruster must not interfere with main drive propeller or rudder.
You can install the thruster off-center and anywhere below the waterline providing
the propellers are deep enough and not obstructed to the sides.
Heavy-duty transom mount L brackets and swim platform mounting extensions in 5”,
10” and 15” lengths are available from Sideshift to allow installation of the thruster in
a variety of scenarios.
