GENERAL
The U360 Steerable Strut Drive mounts on any flat
surface on the bottom of the vessel. The upper and
center housing assemblies are positioned inside
the hull and the vertical and lower housing
assemblies
are
submerged
Attachment to the hull is accompanied by a
mounting flange which is sealed against water
leakage by a marine sealing compound or rubber
gasket and secured by mounting bolts. The
mounting surface must be adequately stiffened to
give solid support in all directions. Align drive so
that the shaft centerline coincides with the fore and
aft centerline of the engine before drilling hull for
mounting bolts. (Figure 1).
INSPECTION
Inspect each U360 Strut Drive Unit upon receipt as
follows:
1. Remove all packing.
2. Visually inspect for shipping damage to paint,
fittings and hoses.
3. Visually inspect for oil leakage.

Installation Instructions
below
the
hull.
INSTALLATION
Install each drive as follows:
1. Apply marine sealant liberally to mounting
surface on hull or apply rubber gasket.
2. Lower
unit
positioning unit so the shaft centerline coincides
with fore and aft centerline of engine.
3. Install
3/8-inch
lockwashers and nuts.
4. Install drive shaft. Make sure that angles of both
joints are equal and lie in same plane. (Figure
2.)
NOTE: A method of aligning the engine and drive is
shown in Figure 3. Two accurate straight edges at
least 18 inches long and a tape measure are
required. Place the straight edges horizontally
along the face of the engine flange and the drive
flange. Measure distance A and B. Distances A and
B must be equal within 1/16" measured 9" out from
shaft centerline. If distances are not equal, move
the engine to accomplish alignment. Rotate straight
edges
90°
and
alignment. After the engine has been securely
anchored the measurements should be rechecked.
CAUTION: Do not attach oil filter to oil reservoir
tank. The weight of the filter will cause damage to
tank fittings.
5. Mount oil filter on bulkhead or suitable bracket.
Note arrow on side of filter for direction of flow.
6. Mount oil reservoir tank on a bulkhead or
suitable brackets.
7. Connect oil/hydraulic lines.
8. Install steering wheel assembly.
9. Mount pressure gauge on engine instrument
panel.
10. Connect hose from oil pressure gauge to port
on oil filter.
