Thrifty not thirsty!
Direct injection = direct savings. Direct fuel injection helps you win the
battle against rising fuel costs. This fuel injection system is partly
responsible for the great fuel-saving features of the HA series, and accounts for far less consumption than any pre-combustion types.
and direct starting. Easy starting is another bonus point scored by the direct injection system.

Effective cooling = efficient combustion.
Maintenance of a constant high temperature by the fresh water cooling system is one of the secrets to the peak combustion characteristics of these engines. It also chops down on lube oil costs and keeps them low, even with long usage.

All-speed stability
Constant temp. cooling = constant performance. The fresh water high temperature cooling also means you get non-fluctuating performance levels at all speeds, especially in low-load conditions. After starting, the ideal temperature for combustion is attained quickly and maintained by thermostatic control.

Reliable and durable
Clean cooling = clear advantages. Another tremendous advantage of this fresh water cooling system is that it reduces thermal wear and stress on cylinder liners and piston rings, prevents corrosion, reduces calcium deposits and makes valuable contributions to the reliability of the engine. Added to this efficient system is an internal oil jet cooling system acting on inner piston walls that reduces heat load at the circumference of the combustion chamber. One more way Yanmar increases durability.

Low vibration = less wear
The minimal vibration of these engines has been achieved through the use of light-weight moving parts and precise balancing, making the machines more durable and less wear prone. Critical components such as stress bearing moving parts, valve trains and combustion
chambers are made of special high grade metals that have proven to be most durable for high speed engines.
