Shire 50 Workboat Inboard Diesel Engine PRM150 Package

Description

Need unyielding commercial barge push power? Select Shire 50 Workboat Inboard Engine packages, coupled to hydraulic PRM150 transmissions for rigorous workboat service. Delivering 50 horsepower at 2,800 RPM from a 2.4-liter block, this engine handles commercial dredging, towing, and maintenance work. Mechanical indirect injection produces steady combustion pressure without electronic injector sensitivity or complex wiring failures.

Solid gray cast iron forms the monolithic engine block, equipped with parent-bore cylinders that withstand continuous load cycles. Heavy 1.5-inch hose tails connect straight to commercial hull skin tanks for closed-circuit cooling. The unit weighs 545 lbs dry including the hydraulic gearbox, with an eight-quart oil capacity and standard SAE 4 transmission housing.

Key Features of Shire 50 Workboat

Commercial contractors buy Shire 50 Workboat inboard engine systems to equip harbor workboats and municipal maintenance hoppers with bulletproof propulsion. The matching hydraulic transmission provides continuous forward and reverse cycling without mechanical clutch wear.

• PRM150 hydraulic gearbox permits full power shifting between forward and reverse directions.
• Cast iron heat exchanger body resists corrosion from engine room humidity and moisture.
• 150-amp commercial alternator provides high DC current for winches and auxiliary power packs.
• High-inertia flywheel keeps shaft rotation steady through weed patches and silt bars.
• Top-access fuel filter allows element swaps without fuel spills onto bilge surfaces.
• Heavy gear-driven sea and skin cooling pumps eliminate belt adjustment requirements.
• Shire 50 Workboat hydraulic responsiveness increases vessel control around lock gates.
• Low mechanical idle speed minimizes wash when mooring along commercial stone quays.

Performance Dynamics Thermal Transfer

Thermostatic valves regulate engine core temperatures between 174°F and 188°F under full continuous workboat duties. The engine generates 114 lb-ft of torque at 1,750 RPM, turning large diameter propellers to push heavy work scows. Rated for M1 continuous commercial operation, it transfers 38 kW of heat to skin cooling tanks. Brake specific fuel consumption averages 220 g/kWh, drawing 0.58 gallons per hour during active towing work.

Exhaust Details Mounting Clearances

The dry exhaust flange accepts 2.0-inch BSP pipe fittings with thermal blankets to fulfill ABYC P-1 inland commercial criteria. Engine bearer brackets align with commercial 24-inch stringer beds, maintaining three inches of clearance above the bottom plate. High-deflection rubber isolators isolate hull frames from harsh engine vibration pulses.

Service Protocols Safety Precautions

Dual Morse cables provide direct physical connections to throttle and transmission control valves for immediate maneuverability. Crews check engine oil and gearbox fluid sight glasses before starting morning shifts. This workboat engine package is not engineered for light speedboats, waterjets, or untreated raw river water cooling circuits.

• Check oil levels on engine and gearbox before each shift.
• Clean primary fuel filter sediment bowls every 100 hours.
• Replace engine lube and secondary spin-on filters every 250 hours.

Warranty Provisions Crated Components

Commercial fleet buyers receive 2-Year or 2,500-Hour limited warranty backing on mechanical engine components. Each crate includes the fully assembled engine, PRM150 gearbox, commercial vibration mounts, complete wiring harness, heavy-duty helm panel, and factory maintenance manual.
