Volvo Penta released the D9 diesel engine, which offered high performance combined with minimal vibrations, resulting in a high degree of onboard comfort. The engine was available in two power output alternatives, 500 and 575 horsepower, and was a powerful alternative for flybridge boats, sportcruisers, and sport fishers of about 40 to 50 feet in length. The D9 has a cylinder volume of 9.4 liters and has a great deal in common with the larger D12 engine, with which was Volvo Penta’s market-leader in its segment. The engine was built entirely in Volvo’s engine plant in Skövde, Sweden, and was designed to be easy to install, even in confined engine spaces. The D9 was fully symmetrical, which further simplified installation. All important service points are easily accessible, making daily inspection a simple matter. The engine has a compact and clean design, and with all fluid filters symmetrically positioned at the rear, the engine was easy to service and maintain. The D9 had a self-diagnostic facility, which indicates at the dashboard if a failure should occur. The engine complies with IMO and the comprehensive emission requirements introduced in Europe and the US in 2006.
