Every 50 Hours Of Operation - Yanmar 2YM15 Operation Manual

PERIODIC MAINTENANCE
Adjusting 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.
