Instructions
Note: Before following these instructions, attach the wheel drive to the wheel (refer to the
ST4000+ Owner's Handbook for details).
Preparation
1. Cut out the appropriate 'wheel spindle' circle (at the center of this template), so you
can place the template over your wheel spindle.
2. Rotate the template to determine suitable locations for the motor tube and bracket:
• You may be able to orientate the wheel drive so the motor tube runs alongside the
pedestal. In this case, proceed to 'Cutting the bracket'.
• There are two alternative slots for the bracket in the back cover of the wheel drive
(Slot 1 and Slot 2).
• Locate the motor tube where:
• a 55 mm (2
1
/8 in) hole can be cut in the bulkhead/pedestal (if required)
• the seal and ring can be secured around the motor tube
• there is sufficient space behind the mounting location to allow at least 10 mm
(0.4 in) clearance around the motor (see diagram below)
CAUTION: 
Mount the drive so the motor tube is as far as possible from the boat's
compass to reduce the risk of deviation.
3. Use the template to mark the locations of the bracket and motor tube.
Cutting the motor tube hole
1. Drill a small pilot hole at the center of the intended motor tube location so you can
check there is sufficient clearance behind the mounting location.
CAUTION: 
Before you cut the motor tube hole, check behind the intended
location for any steering mechanisms, cables or obstructions.
2. Cut a 55 mm (2
1
/8 in) diameter hole at the motor tube location and smooth any
sharp edges.
3. Assemble the ring/seal onto the motor tube:
• fit the metal ring first
• then fit the rubber seal: the seal will self-center on the tube
4. Temporarily mount the wheel and drive onto the spindle, allowing
the motor tube to pass through the hole.
5. Press the seal against the bulkhead/pedestal, orientate the seal as
required, then mark the centers of its mounting holes.
Cutting the bracket
1. With the wheel still in place, hold the bracket under the wheel
drive so you can mark dimension A – the distance between the
mounting surface and the rear edge of the wheel drive front cover.
Note:If the wheel is bent or not running true, dimension A will
change. Measure the shortest distance.
2. Use a hacksaw to cut the pin 10 mm (0.4 in) LONGER than
dimension A. Remove any sharp edges with a file or sandpaper.
3. Position the bracket so the pin is in the middle of the relevant slot. 
Note: the center of the bracket pin should be 154 mm (6.1 in) from
the center of the wheel spindle.
4. Mark the center of the bracket's mounting holes then remove the
wheel and drive.
Attaching the bracket and ring/seal
1. Drill 4 mm (
5
/32
in) diameter pilot holes for the bracket and
ring/seal mounting screws.
2. Attach the bracket using three self tapping screws
(No 10 x
3
/4
in). Note: on fiber-glass surfaces you may
need to replace the mounting screws with suitable
nuts, bolts and washers.
3. Remove the ring/seal from the motor tube, then use
three self tapping screws (No 10 x
3
/4
in) to attach
them to the mounting surface. 
Note: make sure the rubber seal is closest to the
surface (i.e. with the metal ring on top).
Final assembly
1. Attach the drive cable to the socket on the motor
tube, then secure the cable so it is clear of any
moving parts.
2. Fit the wheel and drive back onto the wheel spindle
and fully tighten the wheel nut.
3. Route the cable to the control unit, bearing in mind
the EMC guidelines in the ST4000+ Handbook.
