Volvo Penta D1-20 Marine Saildrive 130S Package

Description

Satisfying EPA Tier 3 and RCD 2 emissions without complex electronic controls is simple with the Volvo Penta D1-20 130S Saildrive Engine. This 3-Cylinder 0.8L package outputs 18.0BHP continuous power at 3,000 RPM matched to a hydrodynamic saildrive leg. Operators must inspect the double hull sealing diaphragm sensor circuit and clean raw water intake slots on strict schedules.

Structural casting uses an ASTM gray cast iron monobloc block featuring parent cylinder bores and an overhead-valve cylinder head. Electrical architecture features a 12V negative ground system powered by a 1.1 kW starter motor and a 115A marine alternator with battery sensor regulation. Dry mass spans 229 lbs excluding the saildrive lower leg. The engine mounting stance occupies 25.9in of length, 17.9in of width, and 19.8in of height, holding 0.74 US gal of oil.

Key Features of Volvo Penta D1-20

Production sailboat builders buy Volvo Penta D1-20 130S saildrive engines to eliminate shaft alignment problems and gland packing leaks. The integrated lower leg package supplies an efficient sailing yacht auxiliary engine repower configuration for racing monohulls and small catamarans up to 32ft.

• Model 130S saildrive leg eliminates propeller shaft vibrations and packing gland drip maintenance.
• Double hull sealing diaphragm includes an acoustic water-intrusion warning sensor for hull safety.
• Naturally aspirated 3-Cylinder block generates smooth rotational balance across the complete operating band.
• Sound-damped air intake filter suppresses suction noise inside small boat cabins.
• Saildrive leg raw water ingestion feeds cooling fluid to the tubular heat exchanger core.
• High-capacity 115A marine alternator restores domestic battery banks during brief motoring runs.
• Mechanical cam-driven injection pumps provide dependable cylinder fueling across changing sea states.

Saildrive Dynamometer Testing Thermal Limits

Dynamometer load verification proves 18.0BHP continuous output and 31 ft-lbs of shaft torque at 3,000 RPM, peaking at 18.8BHP at 3,200 RPM. Raw seawater ingestion through the saildrive leg maintains tubular heat exchanger coolant temperatures stabilized at 180°F under continuous full-load motoring. Exhaust pyrometer temperatures remain under 890°F ahead of the water-injected exhaust mixer. Main journal oil pressure registers 48 PSI at cruising RPM, while crankshaft journal runout measures within 0.0004in TIR across all bearing contact surfaces.

Field Usability Protocols Installation Boundaries

Single-lever sail control levers require 3 lbs of smooth hand effort to advance the mechanical governor across the operating band. This saildrive powertrain is not built for heavy commercial workboats, steel canal narrowboats, or high-speed planing hulls. Never select this sailing yacht auxiliary engine repower package for craft without a reinforced GRP saildrive foundation bed or hulls requiring traditional shaft logs.

• Change engine oil and replace the spin-on lube filter every 150 operating hours.
• Inspect lower saildrive gear lube and replace zinc anodes every 12 months.
• Check mechanical overhead valve lash clearances to 0.008in cold every 500 operating hours.
