SPX-10 Hydraulic Installation Guide for Verado systems
Procedure
Referring to the hydraulic circuit on the following page, modify the Mercury hydraulic
system by installing the Raymarine hydraulic components, as follows:
1. Install the barbed hose fitting (with sealing washer) to port ‘R’ on the Type 1 pump.
2. Fit the 3’ (915 mm) return line low pressure hose over the barbed hose fitting and
secure using the supplied hose clamp.
3. Attach the two 3’ (915 mm) high pressure hoses (with sealing washers) to ports ‘A’
and ’B’ on the Type 1 pump.
4. Attach the UNF Tee fittings (visually inspect the fittings to ensure that the face ‘O’
rings are in place).
5. Attach the 1’ (315 mm) high pressure hoses to the Tee fittings.
6. Attach the barbed Tee fitting to the hose from the Type 1 pump and secure using
the supplied hose clamp.
7. Locate the ‘T’ port Mercury return hose at the back of the Verado helm (leads to
the reservoir on the hydraulic pump module). Identify a suitable location along its
length to install the barbed Tee fitting.
WARNING: Hydraulic fluid
Do not allow hydraulic fluid to come into prolonged contact with your skin.
Thoroughly wash any affected areas. Wear protective nitrile gloves when
working with hydraulic fluid.
8. Cut the return hose, install the barbed Tee fitting and secure using the supplied
hose clamps.
Notes:
(1) Hoses cut or removed from the helm should be held upright until reconnected.
(2) Do not allow hydraulic fluid to drain out of the hoses.
(3) Check and top-up the hydraulic pump reservoir as necessary during installation.
Locate and tag the ‘L’ and ‘R’ Mercury installed hoses at the back of the Verado
helm.
9. Remove the Mercury ‘L’ hose and attach to the Tee fitting on the hose from ‘A’ on
the Type 1 pump.
10. Connect the 1’ (315 mm) high pressure hose from the Tee fitting to ‘L’ on the back
of the Verado helm.
11. Remove the Mercury ‘R’ hose and attach to the Tee fitting on the hose from ‘B’ on
the Type 1 pump.
12. Connect the 1’ (315 mm) high pressure hose from the Tee fitting to ‘R’ on the back
of the Verado helm.
13. Check all connections, fittings and clamps are tight.
14. Carry out the
