8SY-STP 900hp
High Performance V8

YANMAR MOVES UP TO 16 LITERS

Yanmar Marine has announced the second in its new SY-STP series of big-capacity diesel engines for high performance cruisers and motor yachts, this time at 900 hp.
The 16-liter Yanmar 8SY-STP is a 90º V8, designed for more power with less weight, maximized torque at low revs, improved fuel economy, reduced emissions and simplified servicing.
Optimum fuel flow is created with twin turbochargers, charge-air cooling, individual cylinders with four-valve technology and an engine block where fuel supply takes place on the cooler side. Electronic fuel injectors allow the amount of diesel injected and its timing to be controlled precisely, from cold starting to idling and through to open-throttle performance. This results in higher power outputs, lower fuel consumption and less visible exhaust smoke.
This latest Yanmar has an electronic engine management system, monitoring and processing data such as engine speed, boost pressure, coolant temperature and throttle setting. The system adjusts injection timing and the amount of fuel injected in response to changing operating conditions, maximizing power and efficiency. Its communications area network (CAN) protocol permits a total overview of the engine data in real time.

The 8SY-STP is approximately 1651kg (3,637 lbs) fully equipped.

It features individual cylinder heads that offer substantial weight savings and are light enough to be lifted and reinserted by just one person. Together with modular design for fewer maintenance operations, electronic diagnostics and easily accessible service points, routine engine care is simple and economical.

This compact engine measures approximately 1295mm long x 1245mm wide x 1067mm high (51" long x 49" wide x 42" high).

It facilitates easy front-end mounting of power take-offs for other engine-driven equipment. Fresh water is used to cool the entire engine and for the charge-air cooling, which has an extra circuit to provide the coolest possible intake air. This contributes further to reliability and long service life.
The engine is fitted with a high-capacity alternator producing 140 amps at 24 volts, easily maintaining a total battery capacity of 160 amp-hours.

Yanmar Marine expects to show pre-production models at the Genoa Boat Show in Italy and the Fort Lauderdale Boat Show in Florida this October (2003).

The first engines should be available to boatbuilders early in the new year, ready for next boating season (2004).
