FNM 13HPE-110 Inboard Shaft Marine Diesel Engine Package

Description

Repower small commercial watercraft with the FNM 13HPE-110 Inboard Shaft Marine Diesel Engine, generating 110 BHP at 4,000 RPM from a compact 1.3L inline-4 block. This 16-Valve MultiJet common rail engine provides high power-to-weight balance, though the sensitive electronic direct injection demands strict 2-micron fuel pre-filtration and regular zinc anode maintenance in saltwater channels.

Engine architecture combines an ASTM parent-bore cast iron block with a 16-Valve aluminum cylinder head and double overhead camshafts. Electrical components run on a 12V negative ground system supported by a 12V 1.3 kW starter and a 12V 90A marine alternator. Dry weight equals 364 lbs without transmission across an engine stance measuring 27.0in long by 24.0in wide and 25.4in high. The marine oil sump holds 1.19 US gal.

Key Features of FNM 13HPE-110

Harbor launch operators buy FNM 13HPE-110 marine engines to secure high fuel savings on passenger shuttle routes. This commercial workboat diesel engine repower package pairs with ZF 25 and ZF 25A hydraulic marine transmissions.

• MultiJet common rail injection operates at 1,600 bar to eliminate exhaust smoke under acceleration.
• Dual overhead camshaft 16-Valve aluminum head maximizes combustion efficiency across a 4,000 RPM range.
• Seawater-cooled charge air intercooler drops inlet air heat to sustain torque output.
• Dual-circuit heat exchanger isolates engine coolant from raw seawater corrosion.
• Standard SAE 5 bellhousing flange couples flush with an internal flexible marine damper.
• Lightweight 364 lbs dry engine mass prevents stern squat on narrow displacement launches.
• High-output 12V 90A marine alternator supplies continuous electrical power for commercial radar units.

Dynamometer Test Limits Thermal Tolerances

Dyno cell evaluation confirms 80 BHP continuous output at 3,600 RPM and 110 BHP intermittent power at 4,000 RPM. Shaft torque hits 148 ft-lbs at 1,800 RPM. High-pressure injection pressure measures 1,600 bar while the turbocharger maintains 1.5 bar of boost air. Exhaust temperatures before the water-jacketed manifold remain below 1,110°F during full load operation. The dual-circuit cooling system holds internal coolant at 185°F. Main journal runout measures within 0.0003in TIR, and lube oil pressure stabilizes at 45 PSI across a 20° tilt.

Field Operation Maintenance Service Protocols

Electronic throttle linkages provide positive helm feedback with 1 lb of control resistance. Do not drop this light high-speed commercial unit into deep-draft ocean pushboats, river tugs, or heavy displacement barges requiring slow continuous bollard pull. The high-speed rating is targeted for commercial workboat diesel engine repower projects on water taxis and light displacement tenders.

• Drain engine lube oil and replace the spin-on oil filter every 200 operating hours with 5W-40 oil.
• Change primary 2-micron fuel water separator elements every 250 operating hours to protect electronic injectors.
• Inspect and replace dual-circuit heat exchanger sacrificial zinc anodes every 150 operating hours.
