ENGINE TECHNICAL
INFORMATION
These water pumps are powered by a single cylinder,
overhead valve (OHV), air cooled, low emissions engine.
In the State of California, these water pump engines are
certified by the California Air Resources Board to meet
emissions standards for 250 hours. Such certification does
not grant the purchaser, owner or operator of this engine
any additional warranties with respect to the performance
or operational life of this engine.The engine is warranted as
stated elsewhere in this manual.
Power Ratings
The power ratings for an individual engine model are
initially developed by starting with SAE (Society of
Automotive Engineers) code J1940 (Small Engine Power &
Torque Rating Procedure) (Revision 2002-05). Given both
the wide array of products on which our engines are
placed, and the variety of environmental issues applicable to
operating the equipment, it may be that the engine you
have purchased will not develop the rated horsepower
when used in a piece of power equipment (actual "on-site"
power).This difference is due to a variety of factors
including, but not limited to, the following: differences in
altitude, temperature, barometric pressure, humidity, fuel,
engine lubrication, maximum governed engine speed,
individual engine to engine variability, design of the
particular piece of power equipment, the manner in which
the engine is operated, engine run-in to reduce friction and
clean out of combustion chambers, adjustments to the
valves and carburetor, and other factors.The power ratings
may also be adjusted based on comparisons to other
similar engines utilized in similar applications, and will
therefore not necessarily match the values derived using
the foregoing codes.
