Baudouin 12M26.2 Mechanical V12 Marine Diesel Engine

Description

Propel inland river pushboats through high river currents with pure mechanical injection reliability. The Baudouin 12M26.2 Marine Diesel Engine produces 1,200 BHP continuous output from a 31.8-liter V12 block without sensitive common-rail electronics. This mechanical design demands manual valve lash checks every 1,500 hours, requiring dedicated onboard wrench time during scheduled port layovers.

Vermicular gray cast iron forms the monolithic engine block and individual four-valve cylinder heads. Replaceable wet sleeve cast iron cylinder liners feature dedicated inspection handholes cast into the crankcase sides. The 24V isolated-ground electrical architecture powers a 24V starter and 55A marine alternator. Dry engine mass equals 7,496 lbs, requiring engine room envelope measurements of 92.8in length, 55.1in width, and 55.5in height with an SAE 0 flywheel housing.

Key Features of Baudouin 12M26.2

Marine fleet operators buy Baudouin 12M26.2 engines to repower commercial towing vessels with proven mechanical fuel control. Competitive acquisition pricing makes this commercial marine propulsion package an economical choice for pushboats operating on remote waterways with basic fuel qualities.

• Mechanical inline fuel injection pump burns standard marine gas oil without common-rail injector stick.
• Electronic governor regulates fuel rack position to hold steady 1,950 RPM under shifting tow loads.
• Twin turbochargers feed jacket-water charge-air aftercoolers to sustain continuous 1,200 BHP output.
• Keel-cooled closed grid circuit eliminates raw seawater passages inside the engine cooling jackets.
• Crankcase inspection handholes allow direct bearing examinations without dropping the oil pan.
• Deep 30.4-gallon cast iron oil sump extends lube oil service life during continuous towing.
• Standard SAE 0 flywheel housing mates to heavy Masson, Twin Disc, or Reintjes gearboxes.

Dynamometer Bench Load Fuel Verifications

Dyno load cell testing confirms continuous 1,200 BHP output at 1,950 RPM with brake specific fuel consumption averaging 0.342 lbs per horsepower hour. Crankshaft journal runout measures 0.0004in TIR across all induction-hardened main bearing journals. Cylinder exhaust gas temperatures peak at 940°F under full continuous tow loads. Jacket water aftercooler temperatures stabilize at 176°F under sustained full throttle runs. Acoustic noise sensors record 98 dB inside the engine compartment during full torque output of 3,228 ft-lbs continuous rotational force.

Engine Room Usability Service Schedule

Handhole inspection covers unbolt with 25 ft-lbs torque, providing clear access to connecting rod big-end caps. Do not purchase this mechanical marine diesel engine for high-speed planing hulls requiring lightweight aluminum blocks or EPA Tier 4 commercial passenger ferry mandates.

• Change the 30.4-gallon oil reservoir and spin-on lube filters every 500 operating hours.
• Inspect mechanical injector opening pressure and spray patterns every 3,000 engine run hours.
• Check valve lash clearances across all 48 valves every 1,500 hours using feeler gauges.
