Baudouin 6M16 Mechanical Workboat Marine Diesel Engine

Description

Displacement trawlers and harbor launches rely on the Baudouin 6M16 Mechanical Workboat Marine Diesel Engine for reliable continuous propulsion. Operating as a rugged inshore commercial fishing boat engine, this 9.7-liter assembly carries IMO Tier II and CCNR II certification. Tight hull stringer spacing complicates raw-water pump access, while low deck clearance requires care during valve lash adjustments.

Individual cast iron cylinder heads give this Baudouin mechanical inline six diesel high structural rigidity under continuous trawling drag. Replaceable wet sleeve liners inside the 9.7 liter mechanical injection block permit straightforward in-frame overhauls directly inside the vessel. Mechanical direct fuel injection tolerates poor fuel quality without throwing error codes. An isolated 24V electrical architecture stops stray current corrosion on steel hulls. Total dry bobtail weight sits at 1,056 kg (2,328 lbs).

Key Features of Baudouin 6M16

Requesting a Baudouin 6M16 repower quote verifies stringer bed width and shaft down-angle geometry before pulling the old machinery. Simple mechanical controls eliminate costly electrical failures at sea.

• Bore and stroke dimensions of 126 x 130 mm (4.96 x 5.12 in) displace 9.7 L (592 cu in).
• Provides an unconstrained continuous P1 commercial duty rating of 360 BHP (264 kW) at 2,100 RPM.
• A water-cooled charge air intercooler chills turbocharged intake air to optimize combustion density.
• Tubular cupronickel heat exchanger plumbing resists corrosive raw saltwater during heavy operating cycles.
• The standard SAE 1 housing and SAE 14 flywheel match straight shaft marine transmission pairing.
• Standard equipment includes a low RPM high inertia flywheel for smooth displacement trolling.
• Heavy cast mounting feet support the 1,056 kg (2,328 lbs) dry propulsion mass.

Combustion Dynamics and Wheel Torque

Strong low-end torque develops deep wheel thrust early, with the turbocharger establishing positive manifold pressure by 1,300 RPM. Running this 360 hp commercial diesel at full continuous rating consumes roughly 17.6 GPH (66.5 LPH) of Ultra-Low Sulfur Diesel. Keeping wet exhaust gas temperatures below 1,022°F (550°C) protects exhaust valves during long towing runs. Ambient engine room temperatures above 122°F (50°C) force fueling derates. Ensure generous intake air ventilation. Clean mechanical direct injection avoids exhaust slobber during extended harbor idling, delivering workboat commercial marine propulsion.

Engine Room Servicing and Corrosion

Service access dictates maintenance speed in cramped commercial bilges. Checking engine oil requires 380 mm (15.0 in) clearance above rocker covers to withdraw the dipstick cleanly. Crankcase breathers vent oily mist under prolonged full-load runs, requiring periodic hose clearing. Secondary fuel filter changes need small catch basins to isolate diesel spills. Sacrificial zinc anodes on heat exchanger heads demand bi-monthly inspection to halt tube corrosion. Anti-seize paste prevents seized pump fasteners.

• Inspect raw-water pump impellers seasonally for blade cracking.
• Drain the 24.0-liter oil pan using the manual sump drain valve.
• Maintain shaft coupling alignment within 0.05 mm across resilient mounts.
