Sole SDZ-280 High-Output Commercial Marine Diesel Engine

Description

Predawn departures through rough coastal inlets demand immediate throttle response under heavy towing resistance. The Sole SDZ-280 Commercial Marine Engine drives commercial trawlers and pilot vessels with 240 BHP continuous output across an Inline-6 7.1L Deutz-based platform. Seawater aftercooling protects intake air density, though common rail injectors demand strict 2-micron primary filtration to stop high-pressure fuel pump scoring.

Monobloc cast iron casting pairs six replaceable wet sleeve liners with individual 4-valve cast iron cylinder heads. A 24V isolated ground electrical system mounts a 5.5 kW electric starter and an 80A marine alternator. Dry weight totals 1,786 lbs bobtail. Physical mounting stance dimensions span 58.3in long by 32.3in wide and 37.4in high, featuring an SAE 2 bellhousing, SAE 11.5 flywheel, and a 5.28 US gal commercial deep oil sump.

Key Features of Sole SDZ-280

Commercial fleet skippers buy Sole SDZ-280 commercial marine engine units to repower harbor tugs, passenger launches, and fishing vessels. The SAE 2 flywheel housing couples to Technodrive TM 265, TM 880A, ZF 85A, or ZF 280 hydraulic marine transmissions.

• High-pressure common rail fuel injection meters diesel at 1,600 bar for smokeless commercial operation
• Turbocharger with seawater-cooled charge air intercooler yields 240 BHP continuous output at 2,100 RPM
• Individual 4-valve cylinder heads maximize gas exchange and simplify cylinder servicing in cramped engine rooms
• Replaceable wet sleeve cylinder liners allow in-frame overhauls without removing the engine block
• 24V isolated ground electrical architecture prevents galvanic hull corrosion on steel and aluminum vessels
• Deep 5.28 US gal oil sump extends drain intervals during continuous offshore commercial fishing runs
• Tubular heat exchanger cooling isolates raw seawater from internal block water passages

Dynamometer Bench Test Thermal Tolerances

Dynamometer testing certifies 240 BHP continuous power at 2,100 RPM with 272 BHP maximum rating at 2,300 RPM. The seawater-cooled aftercooler maintains intake air temperatures below 125°F under full-load trawling runs. Deep sump oil pressure registers 55 PSI at operating temperature across static bed inclinations up to 15°. Common rail fuel rail pressure maintains 1,600 bar, while crankshaft journal tolerances remain within 0.0006in TIR to safeguard main bearings against high torque reversing loads from heavy reduction marine transmissions.

Helm Operation Scheduled Preventive Maintenance

Electronic CAN-bus throttle controls connect to vessel bridge consoles with zero mechanical cable drag. Do not install this 1,786 lbs 7.1L engine in light planing pleasure boats or shallow draft skiffs that lack the hull displacement to support commercial cast iron machinery mass.

• Evacuate 5.28 US gal of 15W-40 lube oil every 500 operating hours with the fitted sump drain pump
• Replace primary 2-micron fuel water separator elements every 250 operating hours to preserve common rail parts
• Inspect heat exchanger tube stacks, raw water impellers, and sacrificial zincs every 1,000 run hours
