Volvo Penta V8-430A-CE Aquamatic DuoProp Sterndrive Package

Description

Skippers of high-speed offshore runabouts battle sluggish mid-range punch when carrying heavy passenger payloads. The Volvo Penta V8-430A-CE DuoProp Package solves this deficit through performance CNC-ported cylinder heads on a 6.2L V8 generating 430BHP at 6,000 RPM. Direct gasoline injection requires 10-micron fuel filtration, and high-compression pistons demand minimum 91 AKI premium fuel.

A die-cast all-aluminum block integrates cast-in iron liners to handle 6,000 RPM firing frequencies. The performance CNC-ported aluminum cylinder heads feature high-flow ports and variable valve timing. Electrical systems operate on a 12V marine ground with CAN-bus EVC-E integration, a 1.4 kW starter, and a 12V 75A alternator. Package envelope dimensions measure 37.0in long, 30.6in wide, and 32.3in high, weighing 1,087 lbs. Oil pan capacity holds 1.45 US gal.

Key Features of Volvo Penta V8-430A-CE

Flagship boat owners buy Volvo Penta V8-430A-CE DuoProp sterndrive packages to equip 26ft to 36ft sport cruisers with maximum naturally aspirated V8 power. Marine yards choose this package for commercial workboat diesel engine repower hulls converting to high-output gasoline sterndrives.

• Performance CNC-ported cylinder heads maximize intake flow to generate 430BHP at peak RPM
• Direct fuel injection sprays fuel charges straight into combustion chambers for clean burn
• Variable valve timing adjusts camshaft timing across RPM bands to maximize hole-shot torque
• Aquamatic DPS sterndrives use dual counter-rotating propellers to eliminate steering pull and prop walk
• CAN-bus EVC-E electronic controls remove mechanical cable friction and provide smooth electronic shifting
• Closed freshwater cooling loops protect internal aluminum water jackets from corrosive raw seawater
• Serpentine belt systems maintain positive drive grip on the 12V 75A alternator

Bench Dynamometer Load Test Output

Dynamometer test runs prove 430BHP peak output at 6,000 RPM and 330BHP continuous output at 5,200 RPM. Naturally aspirated intake manifold pressures hold at 1.00 bar barometric reference through the high-flow intake plenum. Closed freshwater cooling circuits stabilize block temperatures at 160°F under continuous dyno loading. Engine oil pressure maintains 50 PSI across operational engine speeds. Sterndrive trim permits up to 30° static trailering angles. Crankshaft journal runout remains below 0.0005in TIR to protect bearings against deflection fatigue. Exhaust manifold temperatures stay below 1,220°F.

Field Operation Maintenance Service Rules

Electronic EVC helm levers provide resistance-free throttle and shift actuation with under 2 lbs of hand resistance. Do not install this high-compression gasoline sterndrive package in commercial displacement push-boats or vessels operating on low-grade fuel below 91 AKI octane ratings. Operators must maintain clean fuel filtration and inspect outdrive drive bellows regularly to prevent water intrusion.

• Drain engine oil and change spin-on oil filter cartridges every 100 operating hours
• Inspect DPS sterndrive gear oil, drive bellows, and sacrificial zinc anodes every 100 hours
• Replace the primary 10-micron fuel water separator filter cartridge every 100 engine hours
