Vetus M2.18K Keel-Cooled Compact Marine Diesel Engine

Description

Propel narrowbeam canal launches through the Vetus M2.18K Keel Marine Engine, built to power inland waterway cruisers and maintenance punts. Displacing 635 cc across two cylinders, this naturally aspirated diesel generates 16 horsepower at 3,600 RPM. Swirl pre-combustion chamber fuel injection provides quiet operation, low smoke emissions, and smooth propulsion during continuous navigation in shallow waters.

High-grade gray cast iron forms the monolithic cylinder block, equipped with hardened parent-bore cylinder walls that resist scuffing. The closed fresh water keel-cooling circuit features one-inch beaded push-on hose tails for connection to hull skin tanks. Dry weight without transmission is 212 lbs, supported by a 3.2-quart oil pan, SAE 6 housing, and 0.312-inch hose barb fuel fittings.

Key Features of Vetus M2.18K

Canal boaters buy Vetus M2.18K inboard engine packages to replace raw water cooled engines in silted waterways. The closed-circuit keel-cooling system routes coolant through hull skin tanks to prevent canal weeds and silt from fouling internal cylinder block passages.

• 16 horsepower rating drives small displacement canal craft with steady thrust.
• 75-amp 12-volt alternator charges house battery banks during quiet mooring periods.
• Cast aluminum top cover absorbs mechanical clatter to keep canal boat cabins quiet.
• Closed keel-cooling circuit prevents mud and canal weed clogging in cooling jackets.
• Electric glow plugs initiate rapid combustion down to freezing morning temperatures.
• Vetus M2.18K canal efficiency lowers fuel burn across extended inland waterway passages.
• Flexible rubber engine mounts dampen two-cylinder reciprocating pulses to protect stringers.
• Top-access oil and fuel filters simplify routine maintenance inside shallow engine bays.

Combustion Dynamics Thermal Capacities

Coolant thermostats regulate internal temperatures between 172°F and 186°F under continuous canal motoring operations. The two-cylinder block develops 27 lb-ft of torque at 2,200 RPM, giving small displacement hulls power to maneuver through turbulent lock flumes and silty bridge holes. Rated for M2 continuous duty, thermal heat rejection transfers 12 kW into external skin cooling tanks. Specific fuel consumption averages 245 g/kWh, burning about 0.28 gallons per hour at standard continuous canal cruising speeds in shallow channels.

Exhaust Integration Bay Clearances

Dry exhaust flanges connect to 1.25-inch BSP lagged pipe systems, meeting ABYC P-1 standards for inland vessels. Mounting brackets adjust across 14-inch to 16-inch stringer centers, preserving 2.0 inches of clearance below the oil pan drain plug. Flexible elastomer mounts absorb reciprocating vibration from the hull.

Service Schedules Application Constraints

Direct mechanical Morse cables connect helm control levers straight to governor and gearbox selectors for immediate response. Operators inspect skin tank coolant levels, check oil levels, and monitor belt tension before getting underway. This engine package is not engineered for offshore planing hulls, surface piercer drives, or raw sea water cooling circuits without closed skin tanks.

• Check lubricating oil level on the dipstick before each shift.
• Inspect skin tank coolant recovery bottle every 100 hours.
• Change engine lube oil, gear oil, and filters every 200 hours.

Warranty Terms Package Manifest
