with clean water. 

NOTICE

The safety messages that follow have 
NOTICE level hazards.

It is important to perform daily checks as 
listed in the Operation Manual. Periodic 
maintenance prevents unexpected 
downtime, reduces the number of 
accidents due to poor engine performance 
and helps extend the life of the engine.

See your authorized Yanmar Marine dealer 
or distributor if you need to operate the 
engine at high altitudes. At high altitudes 
the engine will lose power, run rough and 
produce exhaust gases that exceed the 
design specifications.

ALWAYS be environmentally 
responsible.

Follow the guidelines of your 
country’s governmental 

agencies for the proper disposal of 
hazardous materials such as engine oil, 
diesel fuel and engine coolant. Consult the 
local authorities or reclamation facility.

NEVER dispose of hazardous materials by 
dumping them into a sewer, on the ground, 
or into ground water or waterways.

If a Yanmar Marine Engine is installed at 
an angle that exceeds the specifications 
stated in the Yanmar Marine Installation 
Manuals

, engine oil may enter the 

combustion chamber causing excessive 
engine speed, white exhaust smoke and 
serious engine damage. This applies to 
engines that run continuously or those that 
run for short periods of time.
