High End Series with New DPX 500 and DPX 600

Volvo Penta shows further strength with the launch of its two most powerful gasoline units yet, the DPX 500 and the DPX 600. Rated at 475 and 560 propeller shaft horsepower respectively, these two power packs are intended for high-speed boats. With the DPX drive, and its counter rotating twin propellers, and hydraulic steering, the owner gets impressive performance combined with easy handling, safety and reliability. The new engines represent the top of Volvo Penta's "High End Series".

Volvo Penta High End Series includes the DPX 385, 415, 500 and 600. Each unit consists of a big block V8 gasoline engine combined with the DPX drive. The DPX 500 and 600 gasoline engines are for customers who want a performance engine with high driveability, low maintenance and safe boat operation.

The High End Series of gas engines allows Volvo Penta to move up-scale and into the prestige segment and offer a complete range of gasoline engines.

The DPX drive is Volvo Penta's high speed version of the well known Duoprop. It features twin counter rotating steel propellers that give excellent grip in the water with good driveability, response and safety, even at very high speeds. Hydraulic steering is standard and further enhances the ease of driving and safety. Despite its unique performance, the DPX still has the quality, reliability and low service requirements of a standard drive.

High tech engines

All of the High End engines are big block V8s with multiport electronic fuel injection (EFI) for reliability combined with fuel economy and high power output. An audible alarm warns the driver of high temperature or low oil pressure, and if no action is taken the EFI automatically slows the engine down to 2500 rpm.

From the outset, the new DPX 500 and DPX 600 are built for very high output with closed circuit cooling. Many of the parts used are specially designed to withstand the strains imposed, and each unit produced is tested with a minimum one hour dyno break in test. The DPX 600 is completely hand built by specialist technicians.

It is a 92 mph boat and I have had no problems to date. Seems like almost every one who owns a DPX has never had a problem. Can that be said about Bravo driven boats with more than 500hp in front of them? We all know that answer. The only thing I will say about them to the negative, is they are challenging around the docks and close quarter manuevering. Zero radius turns with one in forward and one in reverse, is like being on a teacup ride.
