Baudouin 6W126M Commercial Inboard Marine Diesel Engine

Description

Offshore fishing fleets depend on the Baudouin 6W126M Commercial Inboard Marine Diesel Engine for reliable long-range sea duty. Operating as a commercial fishing trawler propulsion engine, this 11.6-liter design satisfies IMO Tier II and CCNR II emissions limits. Tight stringer bed spacing limits access to bottom oil pan bolts, while low deckheads demand careful exhaust riser planning.

Individual four-valve cast iron cylinder heads give this Baudouin six cylinder commercial diesel high thermal endurance under continuous drag. Replaceable wet sleeve liners inside the 11.6 liter heavy commercial block enable in-frame overhauls without removing the foundation bed. A mechanical inline pump with an electronic governor tolerates varied fuel qualities without throwing codes. The 24V isolated ground electrical system prevents galvanic pitting on metal hulls. Dry weight totals 1,200 kg (2,646 lbs).

Key Features of Baudouin 6W126M

Securing a Baudouin 6W126M repower quote confirms bearer width and propeller shaft rake before removing old engines. Simple mechanical governors provide reliable speed regulation under drag.

• Bore and stroke dimensions of 126 x 155 mm (4.96 x 6.10 in) displace 11.6 L (708 cu in).
• Supplies a continuous P1 commercial duty rating of 400 BHP (294 kW) at 1,800 RPM.
• Reaches maximum intermittent outputs of 450 BHP (331 kW) at 2,100 RPM for heavy pushing.
• Serves as a rugged commercial inboard propulsion engine for cargo transport and towing.
• A water-cooled charge air intercooler cools intake air to maximize combustion efficiency.
• Standard SAE 1 bellhousing connects cleanly to heavy duty marine reverse gear.
• Rigid structural brackets anchor the 1,200 kg (2,646 lbs) dry mass on steel stringers.

Combustion Dynamics and Shaft Horsepower

Strong low-RPM torque produces steady propeller bite early, with the turbocharger establishing positive manifold boost past 1,300 RPM. Working this 450 hp commercial diesel near maximum intermittent rating consumes roughly 22.4 GPH (84.8 LPH), while continuous cruising delivers a low BSFC continuous fuel burn. Wet exhaust gas temperatures must stay below 1,022°F (550°C) to safeguard exhaust valves. Ambient engine room temperatures above 122°F (50°C) force fueling derates. Ensure generous blower airflow. Mechanical direct injection eliminates wet stacking during long trawling runs.

Bilge Maintenance and Anode Inspection

Routine maintenance requires disciplined scheduling on commercial vessels. Checking lube oil requires 380 mm (15.0 in) overhead clearance above rocker covers to withdraw the dipstick cleanly. Crankcase breathers vent oily mist under prolonged heavy towing, requiring periodic hose clearing. Secondary fuel filter spin-on changes demand drip trays to catch diesel spills. Sacrificial zinc anodes on cupronickel heat exchanger caps require bi-monthly checks to prevent tube corrosion. Anti-seize paste prevents seized pipe bolts.

• Inspect raw-water pump impellers seasonally for blade cracking.
• Evacuate the 30.0-liter oil pan using low-mounted manual drain valves.
• Maintain shaft coupling alignment within 0.05 mm across resilient mounts.
