Volvo Penta V8-300A-CE Aquamatic DuoProp Sterndrive Package

Description

Need high torque V8 sterndrive thrust? Select Volvo Penta V8-300A-CE DuoProp Package systems, engineered to power sports cruisers, performance runabouts, and offshore bowriders up to 30 feet. Displacing 5.3 liters across eight V-configured cylinders, this naturally aspirated gasoline engine produces 300 horsepower at 5,800 RPM. Direct fuel injection and variable valve timing ensure crisp acceleration, clean exhaust, and high fuel economy.

High-strength cast aluminum forms the deep-skirt V8 cylinder block and cylinder heads, utilizing cast iron cylinder liners to reduce total engine weight. A closed fresh water cooling system integrates an aluminum heat exchanger, exhaust manifold cooling jackets, and bronze sea water pump. Dry package weight with DuoProp sterndrive is 1,069 lbs, supported by an engine bay envelope matching standard 22.5-inch stringers and quick-connect fuel fittings.

Key Features of Volvo Penta V8-300A-CE DuoProp

Sport boat owners buy Volvo Penta V8-300A-CE DuoProp inboard engine packages to replace aging carbureted sterndrives with clean direct-injection V8 technology. The paired DuoProp drive features twin counter-rotating propellers to eliminate steering torque pull while delivering true straight-line tracking and instant planing lift.

• 300 horsepower rating propels heavy sport cruisers past 45 knots with exceptional throttle response.
• Common-rail direct fuel injection operates at 150 bar to extract maximum energy from regular gasoline.
• Variable valve timing optimizes camshaft phasing for strong low-end acceleration and high-RPM cruising.
• Fresh water cooling isolates block passages from raw lake or saltwater corrosion.
• Dual counter-rotating DuoProp propellers eliminate helm torque and improve reverse stopping power.
• Volvo Penta V8-300A-CE DuoProp efficiency reduces fuel consumption during water sports tow runs.
• Wide-band oxygen sensors adjust air-fuel mixtures in real time across elevation changes.
• Easy drain winterization system empties raw water passages with a single manual hand valve.

Combustion Dynamics Thermal Capacities

Dual thermostats regulate internal coolant temperatures between 160°F and 175°F under continuous planing operations. The V8 block develops 339 lb-ft of torque at 4,000 RPM, giving sport cruisers fast acceleration for towing water skiers and wakeboarders. Operating under recreational marine duty cycles, thermal heat rejection transfers 105 kW into raw sea water circuits. Specific fuel consumption averages 260 g/kWh, burning about 6.25 gallons per hour at standard cruising speeds under loaded displacement conditions.

Exhaust Integration Bay Clearances

Water-jacketed aluminum exhaust manifolds route exhaust gases through the transom plate and propeller hub, meeting ABYC P-1 standards. Engine bearer brackets align with 22.5-inch stringer beds, preserving 2.5 inches of clearance below the cast aluminum oil pan. Flexible rubber shear mounts isolate reciprocating vibration from fiberglass hulls.

Service Schedules Application Constraints

Mechanical push-pull or electronic control cables link helm levers straight to throttle bodies without mechanical binding. Operators check drive trim fluid levels, inspect drive bellows, and verify sea water strainers prior to departure. This gasoline sterndrive package is not engineered for heavy commercial tugs, displacement passenger barges, or unvented engine spaces lacking USCG approved bilge blowers.

• Inspect drive bellows and fluid levels before each shift.
• Inspect and clean sterndrive sacrificial zincs every 100 hours.
• Change engine oil, sterndrive gear lube, and filters every 100 hours.

Warranty Terms Package Manifest

Recreational buyers receive 2-Year limited warranty protection on base castings and sterndrive gear components. The shipping crate contains the V8 gasoline engine, Aquamatic DuoProp sterndrive, transom shield module, complete power trim pump, and bound factory technical service manual.
