Volvo Penta D4-175 175HP Inboard Diesel Marine Engine

Description

The Volvo Penta D4-175 175HP Inboard Diesel Marine Engine resolves heavy hull vibration and sluggish auxiliary performance tracking on heavy displacement cruising motor yachts, commercial passenger tenders, and trawlers. Operating on standard number 2-D marine diesel lines, this heavy-duty four-stroke engine coordinates common rail direct fuel injection systems to replace sluggish mechanical diesels entirely. Vessel skippers can navigate crowded commercial channels or heavy coastal currents safely, letting the turbocharged charge air cooler handle changing load stresses smoothly up to a solid 2800 RPM full throttle range.

Featuring a thermostatically controlled closed-loop fresh water heat exchanger system, the vertical inline-four block prevents internal block hot spots inside unventilated engine beds or steering pedestals. The high-performance 3.669-liter computing block delivers an impressive 175 HP continuous crankshaft output, managing a total charging matrix 115 Amp alternator to keep auxiliary electrical banks charged without power faults. Procuring this premium Sweden-manufactured inboard propulsion block establishes precise low-RPM mechanical drive tracking via an integrated EVC protocol network, backed by an elite 2-Year limited marine factory warranty plan.

Key Features of Volvo Penta D4-175

• Inline 4-Cylinder Four-Stroke Vertical Marine Diesel Engine links an optimized 3669 cc displacement block with high-torque auxiliary profiles into a singular performance propulsion hub.
• Turbocharged with Charge Air Cooler Induction Aspiration forces compressed charge-air into combustion chambers forcefully to generate instantaneous low-end acceleration under heavy boat tonnage.
• Common Rail Direct Fuel Injection CRDI System multi-calibrates fuel pressure curves dynamically to minimize fuel burn while completely eliminating standard diesel smoking.
• Integrated 115 Amps 12 Volts High Output Alternator pushes powerful charging currents deep into heavy marine house batteries to stabilize advanced autopilot and radar networks.
• Volvo Penta Electronic Vessel Control EVC Protocol Network shares real-time engine telemetry, fluid rates, and system diagnostic logs across helm multi-function displays instantly.
• Strict EPA Tier 3, IMO Tier II, and EU RCD 2 Compliance fulfills strict global marine environmental protection laws by optimizing internal thermal combustion efficiency.
• Thermostatically Controlled Closed-Loop Fresh Water Heat Exchanger shields inner cylinder sleeves completely from corrosive raw saltwater exposure via an internal closed loop circuit layer.
• Rugged 103.0 mm Bore by 110.0 mm Stroke Configuration delivers heavy-duty load tracking capabilities across standard displacement hull transit routes.
• Ultra-Lightweight Bobtail Engine Frame weighing 1058 lbs manages high mechanical outputs while optimizing vessel weight distribution to increase total fuel efficiency.
• Universal Fuel Grade EN 590 and ASTM D 975 Compatibility pairs natively with standard global marine diesels to prevent internal fuel pump knocking or component wear.
