VOLVO PENTA AQUAMATIC DUOPROP
5.7/DP

GENUINE V-8
A genuine gasoline V-8 for performance motorboats. With 5.7 liter displacement and eight cylinders, this engine delivers loads of torque and power across the entire speed range. Available with an advanced fuel-injection system, the engine is a perfect match for the Duoprop twin-propeller drive. Power steering and trim are standard.

Engine
5.7 liter gasoline engine in a V-8 configuration featuring: seawater cooling with cast iron cylinder block, cylinder heads and exhaust manifolds, which are specially developed for the marine industry. The exhaust manifolds and risers are EDP treated for increased durability. In addition, the seawater pump is located in the front of the engine for easy accessibility.


Fuel injection
The Multi Port Fuel Injection system is monitored by an Electronic Control Module (ECM) and gives the following ad vantages: more responsive and smoother acceleration, excellent turn key starts in all weather conditions, smooth reliable idling, reduced fuel consumption, and improved control of emissions.
Additional features built into the system include: engine knock control for compensation of less than perfect
gasoline, over speed protection, rpm reduction of the engine for low oil pressure and high engine temperature,
platinum tipped spark plugs for longer life and trou ble free starts, altitude compensation for air density, and self diagnostic capabilities. Also, there are two fuel pumps for low and high pressure respectively.

EVC/EC - Plug and go (option)
EVC Electronic Vessel Control is the latest development in engine control and instrumentation for marine engines. It offers a higher level of integration with your boat: speed, tank level, depth and surface water temp as well as trip computer integrated into a uniform instrumentation are some of the new thrilling options offered by EVC.
EVC makes boating easier and safer, offering twin engine and power trim synchronization and adjustable power trim limits. EVC is scalable from one station up to four, from a classic dashboard up to an advanced driver information system. The system is built on the latest automotive technology with waterproof connectors, so it’s just plug and go.

Aquamatic sterndrive
The Duoprop drive with its twin counter-rotating propellers features exhaust out lets through the propeller hub and cavitation plate producing a harmonious drive unit with unbeatable characteristics in the boat in terms of speed, acceleration, steering, maneuvering, fuel economy and less noise and vibration.
The drive is equipped with a cone clutch for easy and smooth shifting, pattern-matched spiral bevel gears for optimum strength and minimum gear whine, a break-away shaft coupling to prevent costly drive train repairs, and sacrificial zincs located both on the drive and transom shield.
The drive is equipped with easily maneuvered hydraulic power trim for obtaining the best running position at different sea and load conditions.
A choice of stainless steel and aluminum propellers are available for different applications.
The 5.7 features standard power steering for maximum driving comfort.

Electrical system
Electrical system features a 12 V corrosion-protected marine electrical system which meets the U.S. Coast Guard requirements. The engine is wired for easy plug-in connection to the instrument panel. The engine electrical system and the electric hydraulic power trim is protected by a 50 A circuit breaker and comes equipped with a 75 A alternator. Full instrumentation including trim gauge and wiring harness (option on certain markets).
