Sole Mini 55 Turbo Inboard Marine Engine Gearbox Package

Description

Repower cruising sailboats with the Sole Mini 55 Turbo Marine Engine package to gain reliable propulsion in restricted engine spaces. Displacing 1.8L across four cylinders, this turbocharged unit yields 47 BHP continuous power at 2,800 RPM. Closed heat exchanger cooling isolates seawater corrosion, though turbocharger oil feeds require strict 200 operating hour filter changes to preserve rotor bearings.

Cast iron block metallurgy joins four parent-bore cylinders to an OHV monobloc cast iron cylinder head. A 12V negative-ground electrical system mounts a 2.0 kW starter motor and a 95A marine alternator. Dry weight measures 386 lbs before transmission installation. The compact engine stance spans 29.2in long by 20.3in wide and 24.0in high, supported by a 1.45 US gal oil sump capacity that drops into standard 38 to 44 ft sailboat hulls.

Key Features of Sole Mini 55 Turbo

Cruising yacht skippers buy Sole Mini 55 Turbo marine engine gearbox packages to replace aging auxiliary diesels in medium displacement sailboats. The factory package couples a Technodrive TMC 60P or TMC 260 marine gearbox to the bellhousing.

• Marine turbocharger with water-cooled exhaust elbow boosts 1.8L displacement output to 47 BHP continuous rating
• Bosch type in-line mechanical fuel injection pump meters fuel without delicate electronics
• Tubular heat exchanger cooling isolates corrosive seawater from engine block water jackets
• High-capacity 95A marine alternator charges house battery banks during coastal motoring
• Monobloc parent bore cast iron construction prevents thermal cylinder distortion under turbo boost
• Flexible marine torsional damper plate absorbs engine firing pulses ahead of transmission input splines
• Neoprene impeller raw water pump circulates cooling water through copper-nickel heat exchanger tubes

Dynamometer Output Turbo Bench Tolerances

Dynamometer testing certifies 47 BHP continuous power at 2,800 RPM with 52 BHP maximum power at 3,000 RPM. Heat exchanger circulation stabilizes closed circuit coolant temperatures at 175°F under full turbo boost. Sump oil pressure holds at 46 PSI at operational temperature across static installation inclinations up to 20°. Indirect fuel injector break pressure measures 140 bar, while crankshaft journal tolerances remain within 0.0006in TIR to preserve main bearings against alternating prop thrust loads in rough coastal seas.

Helm Operation Scheduled Service Protocols

Mechanical control cables actuate throttle and shift arms with under 3 lbs of push-pull resistance. Do not install this 1.8L turbocharged engine in shallow draft canal punts or light displacement skiffs where low exhaust temperatures promote soot buildup inside the turbine housing.

• Drain 1.45 US gal of engine oil every 200 operating hours with the fitted sump drain pump
• Replace the spin-on canister fuel filter every 400 operating hours to protect injection pump plungers
• Inspect the raw water pump impeller and heat exchanger zincs every 500 operating hours
