YANMAR 6LY2A-STP - 440hp
Why A Six? The ability to slot an engine as low down as possible in the vee of the boat has been critical.
The straight six has thus become the configuration of choice, as the crankshaft is still not so long as to require heavy strengthening, there is more capacity advantage over a four, and a six is far narrower than a V-eight.

Yanmar's 6LY series has a formidable lineup of engines that have already achieved victory in international powerboat races. The high power- to- weight ratio, the low slung configuration, the virtually square end profile of 708 x 708mm (28 x 28 in) for maximum compactness, and the intercooler turbo are all here.
The mountability is excellent due to its flat top narrow profile.

This engine has muscle and endurance with the following features:

• Race proven performance making a fast boat faster. Power-to-weight ratio is even more startling. Endurance and fuel economy are at a level that only a diesel could achieve.
• It follows current user trends, the demand for more power and more speed. And because it is a diesel, the standard fuel tanks can produce extended range.
• Direct injection using ultra-high pressure fine mist injectors makes for excellent economy together with superb performance, yet there are savings, precious energy savings, and an increase in safety that accompanies a diesel.
