Baudouin 6W105M Inshore Commercial Marine Diesel Engine

Description

Coastal fishing captains depend on the Baudouin 6W105M Inshore Commercial Marine Diesel Engine for reliable daily harbor transits. Serving as a dependable coastal fishing vessel marine diesel, this 6.75-liter assembly satisfies IMO Tier II and CCNR II emissions limits. Tight stringer spacing complicates port-side raw-water pump servicing, while compact overhead room requires careful exhaust elbow routing inside small engine hatches.

Durable cast iron cylinder heads give this Baudouin six cylinder workboat diesel outstanding structural stamina under heavy propeller loading. Replaceable wet sleeve liners inside the 6.75 liter mechanical diesel block allow straightforward in-frame overhauls without removing the pan from the bearers. A mechanical inline pump with an electronic governor tolerates contaminated marine fuel oil. The 24V isolated ground electrical system protects aluminum and steel hulls from galvanic corrosion. Dry weight totals 810 kg (1,786 lbs).

Key Features of Baudouin 6W105M

Securing a Baudouin 6W105M repower quote confirms mount centers and shaft drop angles before craning out old engines. Simple mechanical architecture minimizes electrical troubleshooting at sea.

• Bore and stroke dimensions of 105 x 130 mm (4.13 x 5.12 in) displace 6.75 L (412 cu in).
• Supplies a continuous P1 commercial duty rating of 185 BHP (136 kW) at 2,100 RPM.
• Reaches maximum intermittent outputs of 252 BHP (185 kW) at 2,500 RPM for speed.
• Serves as a rugged prime mover for inboard workboat marine propulsion in rough coastal waters.
• A turbocharged charge-air intercooler cools induction air to optimize in-cylinder oxygen density.
• Standard SAE 3 bellhousing supports straight shaft marine transmission pairing.
• Structural mounting brackets securely anchor the 810 kg (1,786 lbs) dry engine mass.

Combustion Dynamics and Fuel Burn

Strong low-RPM torque produces fast throttle response, with the turbocharger building positive manifold pressure by 1,400 RPM to lift working hulls over their bow wave. Running this 250 hp commercial diesel near maximum intermittent rating consumes roughly 12.8 GPH (48.5 LPH), while steady displacement cruising yields a reduced cruise GPH fuel rate. Keep wet exhaust gas temperatures below 1,022°F (550°C) to protect exhaust valve seats. Ambient engine room temperatures above 122°F (50°C) force fueling derates. Ensure generous intake ventilation. Direct mechanical injection prevents wet stacking during extended harbor trolling.

Bilge Clearances and Corrosion Upkeep

Compact engine flats demand organized routine maintenance. Checking lube oil requires 350 mm (13.8 in) clearance above rocker covers to withdraw the dipstick cleanly. Crankcase breathers vent oily mist under heavy load, requiring periodic hose clearing. Secondary fuel filter changes need small drip basins to catch diesel spills. Sacrificial zinc anodes on heat exchanger caps require bi-monthly checks to halt galvanic pitting. Anti-seize paste prevents seized pump bolts.

• Inspect raw-water pump impellers seasonally for blade cracking.
• Drain the 18.0-liter oil sump using low-mounted manual drain valves.
• Maintain shaft coupling alignment within 0.05 mm across resilient mounts.
