Aquamatic Sterndrive Gasoline Engine Range

Aquamatic – the Sporty Choice

Ever since its introduction in 1959, the Aquamatic has catered to demanding boaters looking for the perfect combination of reliability and performance. The Aquamatic Gasoline engines delivers robust low-end torque, exhilarating high-end power and exceptional mid-range response. Sporty and sharp, yet responsive and fuel-efficient, it’s the perfect choice for both leisure cruising and speedy watersports.

Features

The High-Performance Sterndrive Package

The Volvo Penta Aquamatic Sterndrive, available with a wide range of sporty yet fuel-efficient gasoline engines, offers boaters the ultimate solution for 20–45 ft leisure crafts. From the controls to the engine, and all the way to the drive and propellers, it's engineered to work seamlessly together. You’ll be able to enjoy impressive benefits such as:

 

  • Low CO2 and exhaust emissions
  • Excellent low-speed maneuverability
  • Beach and shallow water tilt
  • Allows for a swim platform
  • Joystick control


Options

Customized for Greater Control

The Aquamatic Sterndrive can be extended with unique features and smart options such as Tow Mode, Cruise Control or Powertrim Assistant. By integrating the drive with the optional Electronic Vessel Control (EVC), you open the door to endless advantages and benefits such as full monitoring, protection and diagnostics for both engine and transmission. More control, more functions, more fun on the water.

Quicker acceleration and higher top speed. Our solution does not only give you better performance, it does it at a lighter weight, with lower fuel consumption and with fewer horsepower.

Features and Benefits

Clean transom, increased comfort

With an uncluttered transom you will have easy access to the water, and you can do so with less exposure to exhaust fumes. A true win for boaters who fancy, for example, watersports or diving. Since almost half of the time boating involves idling, it’s good to know that CO emissions are dramatically reduced at idle – exceeding current US and EU, emission requirements.

Efficiency you can feel

The larger effective propeller blade area of the Duoprop makes the Aquamatic's driveline more efficient – saving you up to 30% on fuel consumption. Direct fuel injection enables you to get more energy from each and every drop of fuel. On top of this, the Variable Valve Timing allows each movement of the intake and exhaust valve to be optimized for speed and load. Put together, it translates into higher torque and acceleration across the full range of RPM’s. Explore the propeller range to see the advantages available for your vessel.

Propellers
Focused on fun

Volvo Penta Speed Control automatically adjusts the throttle to maintain constant engine speed during load changes, like when a wake boarder cuts hard, during turns or in shifting seas. The engine makes micro throttle adjustments so the operator can concentrate fully on having fun instead.

Increased onboard comfort with silent shifting

The Aquamatic sterndrive features silent shift, which provides a seamless and soundless shifting.

Keeping water where it belongs

It’s a no-brainer. Aluminum blocks and fresh water cooling are made for marine use. Eliminating exposure to saltwater not only provides greater engine durability, it also significantly improves a boat’s resale value.

Superior performance

We refuse to accept the compromise of a fixed camshaft. With direct injection and variable valve timing, you get higher torque and acceleration across the full range of RPMs. Think of it as extra power available to you, at any speed.

Quiet & clean

Not only can you have a conversation at the transom, you can do so without exposure to exhaust fumes. Since almost half of the time boating involves idling, it’s good to know that CO emissions are reduced by 95% at idle. We make the cleanest propulsion engines in the market today.

Keeping corrosion at bay

Volvo Penta's stand drives are treated with corrosion resistant material and then covered with three layers of marine paint for even more protection. Salt or brackish water boaters may want to upgrade to OceanX's proprietary titanium-ceramic coating that is highly durable, flexible and covers the entire drive. The coating greatly improves corrosion resistance – up to four times more resistant – making OceanX perfect for salt water or brackish boating.

Focused on fun

Introduced in 2008, Volvo Penta Speed Control automatically adjusts the throttle to maintain constant speed during load changes, like when a wake boarder cuts hard, during turns or in shifting seas. The engine makes micro throttle adjustments so the operator can concentrate on fun.

Service simplified

Our next generation engines share common parts and common service locations on the engine package, across the full lineup. This means easy serviceability and parts availability. Extended maintenance intervals reduce the total cost of ownership.

Easy Drain - Engineered for marine demands

The engine's aluminum blocks and fresh water cooling is constructed specifically for marine use. For greater durability, the engines inner components are fully protected from exposure to salt or sea water and are cooled through an internal water cooling system. And with the convenient Easy Drain solution, you quickly and easily drain all the raw water from your engine – with a single push of a button.

Features

Direct fuel injection

The move from multi-port technology to direct injection means atomized gas enters the combustion chamber at 2250 psi. Compression ratios of up to 11.5:1 create a cleaner burn and fewer emissions. So more energy comes from each drop of fuel.

Variable valve timing

We refused to accept the compromise of a fixed camshaft. Variable valve timing now allows each movement of the intake and exhaust valve to be optimized for speed and load. You’ll have higher torque and acceleration across the full range of RPM’s.

Lightweight aluminum block

Our new lightweight aluminum blocks weigh 41 lbs. less than older cast-iron models. Low-friction, lightweight pistons and a cast aluminum oil pan help us provide up to 15% improvement in the power-to-weight ratio.

Fresh water cooling

It’s no secret, engines with fresh water cooling last longer and run better. Our closed loop cooling system eliminates exposure to saltwater, providing greater engine durability and higher resale value.

Wideband oxygen sensors

Our new wideband oxygen sensors read a greater range of air/fuel values. Now engine performance is optimized regardless of altitude, weather or variable fuel blends.

Clean & powerful

On the water you’ll notice exhaust fumes are virtually eliminated, because these are the cleanest marine gas engines on the market today. CO emissions are reduced by 95% at idle, exceeding current EPA, and future EU, emission requirements. Volvo Penta Next Generation gasoline engines are five times cleaner than outboards at a similar horsepower.

The better alternative

The Aquamatic combines the benefits of both inboard as well as outboard systems. These benefits with the counter-rotating twin propellers, the Duoprop, renders unrivaled and fuel-efficient performance with responsive handling and safe grip. Compared with the outboard engine, the sterndrive engine is placed lower and more forward in the boat. In rough sea conditions, this makes for a more comfortable ride.

Compared to outboards

  • Duoprop for better handling and performance
  • Freshwater cooling as standard for longer service life
  • Lower center of gravity – a more comfortable ride
  • Engine safely inside the boat – longer service life
  • Higher theft protection – engine built into the boat
  • Optional Powertrim assistant and Tow-mode with Electronic Vessel Control (EVC)
  • Uncluttered transom – easy access to the water
  • Increased fuel economy

Compared to inboards

  • Reduced sound and vibrations – better onboard comfort
  • Improved handling and easier maneuvering
  • Compact, integrated installation at the stern gives more onboard space
  • Duoprop for better handling and performance
  • Higher fuel efficiency – better thrust angles give you better performance
  • Kick-up function on drive for impact protection
  • Exhausts emitted through drive, into prop and washed away from boat
  • Powertrim and optional Powertrim assistant to automatically optimize ride
