YANMAR 6LY3 FEATURES
AND APPLICATIONS
The engine is equipped with a marine
gear. The marine gear output shaft
connects with the propeller shaft. In order
to obtain full performance from your
engine, it is imperative that you check the
size and structure of the hull and use a
propeller of the appropriate size. As new
boats are used, owners add additional
equipment and completely fill the fuel and
water tanks adding to the overall
displacement (weight) of the vessel. Extra
canvas enclosures, bottom paint, and
bottom fouling can add additional hull
resistance. It is recommended that a new
vessel be propped so the engine can
operate at 100-200 rpm above maximum
rpm to allow for some added weight and
hull resistance. Failure to do so can lead to
reduced vessel performance, lead to
increased smoke levels and cause
permanent damage to your engine.

The laws of some countries may require
hull and engine inspections, depending on
the use, size and cruising area of the boat.
The installation, fitting and surveying of
