Every 50 Hours Of Operation - Yanmar 1GM10 Operation Manual

PERIODIC MAINTENANCE
Adjusting the Marine Gear Control
Cable
1. Check that the control lever moves to
the correct position when the remote
control cable handle is moved to the
NEUTRAL, FORWARD and REVERSE
positions.
2. Use the NEUTRAL position as the
standard for adjustment. When there is
deviation, loosen the bracket for the
shift control cable on the marine gear
and adjust its position as necessary.
Adjusting the Propeller Shaft
Alignment
The flexible engine mounts are compressed
slightly during initial engine operation and
may cause misalignment between the
engine and the propeller shaft.
After the first 50 hours of operation, the
alignment should be checked and
readjusted if necessary. This is considered
normal maintenance and the adjustment
requires specialized knowledge and
techniques. Consult your authorized
Yanmar Marine dealer or distributor.
