Gear Engagement-Emergency Procedure. 69 Steering And Trim-Manual Override - Mercury Zeus 3000 Series User Manual

Section 3 - On the Water
4. Locate the forward gear solenoid on the port side of the affected transmission (the wire
is tagged "Forward Gear").
NOTE: Do not disturb the reverse gear solenoid on the starboard side of the transmission
(the wire is tagged "Reverse Gear").
5. Using a 3 mm hex‑head wrench, turn the solenoid screw in the center of the top of the
forward gear solenoid clockwise until it stops.
6. The transmission is now manually engaged in the gear and will not respond to the helm
controls for shifting in and out of that gear.
A spinning propeller, a moving boat, or any solid device attached to the boat can cause
serious injury or death to swimmers. Stop the engine immediately whenever anyone in
the water is near your boat.
7. Ensure that the area around the propellers is clear before starting the engine since the
propeller will be turning whenever the engine is operating.
IMPORTANT: The engine does not start with the ERC lever in gear, even though the drive
is manually engaged in a gear.
8. When you are ready to start the engine, position the ERC lever in neutral gear before
turning the key switch to the start position.
NOTE: Due to the extra load of turning the drive gears and propeller, the starter may turn
slower when starting the engine connected to the drive in the emergency setting.
9. Use extra care and caution when operating your boat in this emergency mode. On the
drive with the manually engaged gear, you must turn that engine off to stop the propeller
from turning or providing thrust.
NOTE: Putting the drive with the gear manually engaged into reverse stops the engine.
10. Immediately take your boat to an Authorized Cummins MerCruiser Diesel Repair
Facility and inform them that the drive gear has been manually engaged.
Steering and Trim—Manual Override
The steering and trim system operate using a hydraulic manifold fitted with control
valves. If a malfunction occurs in the manifold for the steering and trim system, VesselView
should display a fault code. The steering actuator, trim cylinder, or both may not respond
to helm control resulting in the loss of normal steering or trim control.
