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.
Check for any unusual noise and vibration
in the engine / boat hull, while increasing
and decreasing the engine speed
gradually.
If there is unusual noise and / or vibration,
this maintenance requires specialized

distributor to adjust the propeller shaft
alignment.

hours thereafter or monthly, whichever
comes first.
