Gear Engagement—Emergency Procedure
If a transmission or electrical system is damaged or has experienced a condition resulting in a fault such that a transmission does
not respond to the helm controls, it is possible to manually engage a gear. In an emergency you can manually place a transmission
into gear by using a suitable wrench to actuate the appropriate gear shifting solenoid.
Note the following:
•
We recommend using the drives that are operational rather than locking and operating a drive that is not functioning properly.
•
Auto Heading and Track Waypoint will work when emergency gear engagement is in use.
•
Moving the ERC handle into reverse stops the engine.
!
CAUTION
Locking the transmission in gear using the emergency procedure renders the helm’s shifting control inoperable. Drive carefully
with the gear lock engaged. To shift out of gear, turn the key switch to "OFF."
1. Determine the transmission that is not engaging a gear.
2. Stop the engines and remove the key from the key switch.
!
WARNING
Engine components and fluids are hot and can cause serious injury or death. Allow the engine to cool before removing any
components or opening any fluid hoses.
3. Remove the drive cover of the affected transmission. Refer to
Section 5—The Drive Cover
.
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.

WARNING
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.
