VEGE Remanufactured VMG30 3.0L 181ci Marine Industrial Long Block Engine

Description

Severe marine exhaust gas dilution and bore wash vanish after dropping in the VEGE Remanufactured VMG30 3.0L Long Block Engine. Engineered for marine commercial long block repower needs, this 181ci 4-Cylinder setup delivers 140HP. Shop hands must verify distributor drive gear engagement depth against the intermediate camshaft boss before torquing down the marine ignition housing.

The casting incorporates dense ASTM A48 Class 30 gray iron throughout the crankcase to neutralize raw salt water corrosion risks. This VEGE engine core utilizes nitrided cast iron camshaft lobes paired with stellite exhaust seats. Electric starter draw requires 12V 165A cranking demand. Engine dry mass reaches 365 lbs inside a 24in length, 22in width, 25in height mounting stance with 4.5 quarts sump capacity.

Key Features of VEGE VMG30

B2B marine fleet buyers buy VEGE VMG30 commercial long block units to restore working vessel operational readiness without purchasing costly complete crate packages. Every production run matches precise industrial engine rebuild factory specifications.

• Marine-grade brass freeze plugs resist galvanic cooling jacket oxidation inside harsh raw-water cooling systems.
• Cast nodular iron crankshaft features micro-polished journals holding 0.0014in hydrodynamic oil film clearance.
• Hardened exhaust seat inserts prevent valve recession during prolonged wide-open throttle commercial operation.
• Hypereutectic aluminum pistons resist thermal ring-land pinch at elevated marine operational temperatures.
• Precision ground balance weights limit torsional crankshaft twist under rapid marine propeller loading.
• VMG30 commercial core casting incorporates reinforced bellhousing mounting pads to handle heavy outdrive thrust loads.
• Heavy-duty mechanical fuel pump pushrod channel receives line-reamed alignment for smooth pump stroke.

Marine Dyno Load Thermal Limits

Brake dynamometer trials establish 140 continuous BHP and 177 ft-lbs torque at 4400 RPM continuous operational rating. Galley pressure maintains 45 PSI at 190°F oil sump temperature, while exhaust gas temp tops out at 1150°F during full throttle load. Dynamic bench sensors verify cylinder compression at 170 PSI across every bore with zero balance deviations exceeding 3%. Crankshaft thrust runout registers 0.0003in TIR on the VMG30 long block engine.

Vessel Installation Guidelines Operating Restrictions

Mechanical marine throttle cable linkage requires 6 lbs actuation resistance at the carburetor bracket. This powertrain is NOT manufactured for closed-loop modern catalytic automotive platforms requiring downstream oxygen sensor control modules. Marine service technicians must execute standardized shop protocol during checkout.

• Replace initial break-in engine oil at 20 operating hours under variable load.
• Adjust mechanical flat-tappet valvetrain lash to 0.000in cold clearance plus three-quarters turn preload.
• Check intake manifold retention hardware after the initial 10 thermal engine cycles.

Warranty Statement Shipping Crate Manifest

Every commercial build complies with VEGE assembly standard guidelines backed by a 2-Year 24,000-mile marine commercial warranty. The banded transport pallet carries the sealed engine block, steel oil pan, circulating water pump, timing case cover, oil pickup screen, and verified dyno run card.
