• If the ambient temperature is below
-16°C (+5°F), rubber components such
as gaskets and seals will harden causing
premature engine wear and damage.
• Consult your authorized Yanmar Marine
engine dealer or distributor if the engine
will be operated outside of this standard
temperature range.
Never engage the starter motor while the
engine is running. Damage to the starter
motor pinion and/or ring gear will result.
