Sole SK-60 Compact Commercial Diesel Engine Gearbox Package

Description

Does your harbor launch or fishing tender stall when battling heavy mooring tides? The Sole SK-60 Compact Commercial Diesel package powers small workboats with 53 BHP continuous output from a 4-Cylinder 2.4L Kubota base. Naturally aspirated induction eliminates turbocharger maintenance, though cooling water intake strainers demand routine checks to prevent floating seaweed blockages in harbor shallows.

ASTM cast iron casting forms the monobloc crankcase with four parent-bore cylinders and an OHV cast iron cylinder head. A 12V negative-ground electrical system pairs a 2.0 kW starter motor with a high-capacity 120A marine alternator. Dry weight equals 529 lbs without transmission. Mounting chassis envelope dimensions measure 34.4in long by 21.3in wide and 25.6in high, supported by a 2.51 US gal lube oil sump capacity.

Key Features of Sole SK-60 Compact

Commercial harbor operators buy Sole SK-60 compact commercial diesel engine packages to repower mooring tenders, displacement fishing boats, and heavy cruising sailboats. The factory package couples a Technodrive TM 345 hydraulic or TMC 260 mechanical transmission to the bellhousing.

• Kubota industrial base engine produces 53 BHP continuous power at 2,600 RPM for workboat operations
• Bosch Mini mechanical indirect fuel injection pump provides steady diesel metering without electronic modules
• High-output 120A marine alternator supplies ample charging current for auxiliary deck machinery and electronics
• Tubular heat exchanger cooling isolates raw seawater from engine cylinder water jackets
• Monobloc parent bore cast iron construction prevents cylinder distortion during continuous towing work
• Flexible marine torsional damper plate absorbs engine firing pulses ahead of transmission input gears
• Low-restriction intake silencer lowers combustion roar inside small vessel pilot houses

Dynamometer Output Thermal Heat Specifications

Dynamometer bench tests verify 53 BHP continuous power at 2,600 RPM with 60 BHP maximum output at 2,700 RPM. Tubular heat exchanger flow stabilizes closed circuit coolant temperatures at 175°F under full-load towing runs. Lube oil pressure holds at 46 PSI at normal operating temperature across static bed inclinations up to 20°. Indirect injector break pressure is set at 140 bar, while crankshaft journal tolerances remain within 0.0006in TIR to preserve main bearings against continuous hydraulic transmission thrust and high torque reversing maneuvers.

Cockpit Controls Preventive Maintenance Schedules

Push-pull helm cables operate throttle and transmission selector levers with under 3 lbs of hand force. Do not specify this naturally aspirated 2.4L engine for high-speed planing launches or heavy commercial barges over 45 ft that require high continuous shaft horsepower.

• Evacuate 2.51 US gal of lube oil every 200 operating hours using the fitted brass sump drain pump
• Replace the primary spin-on canister fuel filter every 400 operating hours to protect injection pump plungers
• Inspect the neoprene raw water pump impeller and heat exchanger zincs every 500 operating hours
