Vetus M2.13 Compact Inboard Shaft Marine Diesel Engine

Description

Repowering a small sailboat often presents severe engine compartment space constraints and strict weight thresholds. The Vetus M2.13 Inboard Marine Diesel Engine resolves this issue through a compact 2-Cylinder 0.6L platform producing 11.8BHP continuous power at 3,200 RPM. Operators must calibrate engine idle speeds to avoid low-RPM two-cylinder shaking and check heat exchanger anodes on strict schedules.

The structural base pairs a monobloc ASTM cast iron cylinder block with integrated parent bores and a cast iron overhead-valve cylinder head. Electrical power runs on a 12V negative ground system fitted with a 1.2 kW starter motor and a 75A marine alternator. Dry weight totals 172 lbs without transmission. The compact mounting stance measures 19.1in long by 18.1in wide and 21.3in high, serviced by a 0.69 US gal lube oil pan.

Key Features of Vetus M2.13

Small sailboat sailors buy Vetus M2.13 inboard marine diesel engines to secure dependable harbor propulsion with minimal fuel consumption. The compact architecture aids inland waterway narrowboat propulsion engine installations across tight engine boxes.

• Mechanical indirect fuel injection with in-line injection pump ensures reliable cold starting in marine environments.
• Cast aluminum acoustic top cover reduces high-frequency mechanical valve gear clatter in small cabins.
• Integrated tubular heat exchanger stabilizes engine jacket temperatures in raw saltwater conditions.
• Marine bellhousing accepts flexible torsional dampers for direct mating with Technodrive TMC 40P transmissions.
• High-output 75A marine alternator restores auxiliary battery banks during short harbor motoring periods.
• Neoprene impeller seawater pump circulates cooling water directly into the water-injected exhaust bend.
• Cast iron monobloc construction dampens natural internal cylinder combustion pulses.

Dynamometer Load Bench Test Data

Dynamometer load cell testing confirms 11.8BHP continuous power and 21 ft-lbs of shaft torque at 3,200 RPM, reaching 13.0BHP at 3,600 RPM. Exhaust pyrometer temperatures hold under 880°F before entering the water-injected exhaust elbow. The closed-circuit freshwater loop stabilizes at 178°F through the tubular heat exchanger under continuous full-load runs. Lube oil pressure maintains 45 PSI at operational RPM, while crankshaft journal concentricity checks confirm runout held within 0.0004in TIR across all journal surfaces.

Field Operation Guidelines Installation Limits

Mechanical throttle cables require 3 lbs of pull force to shift the internal governor arm across the speed band. This lightweight diesel is not built for heavy commercial work barges, deep-draft fishing craft, or planing tenders. Never attempt an inland waterway narrowboat propulsion engine repower with this engine on steel hulls exceeding 26ft in total waterline length.

• Drain lube oil and change the spin-on oil filter every 150 operating hours.
• Inspect the raw water rubber impeller and replace zinc anodes every 12 months.
• Check mechanical overhead valve lash clearances to 0.010in cold every 500 operating hours.
