Cummins QD 17MDKDP-8111A

Description

During extended offshore tournament fishing runs, the Cummins QD 17MDKDP-8111A Marine Generator produces 17 kW continuous single-phase current at 1,800 RPM. Driven by an unstressed 2.434-liter four-cylinder diesel engine, this 60 Hz marine auxiliary power plant drives extensive multi-zone chilled water air conditioning, large tuna tube pump banks, and heavy galley appliances aboard luxury convertibles without experiencing engine lugging.

Heavy-duty gray cast iron block architecture provides structural mass to attenuate low-frequency harmonic drone throughout composite hulls. The rotating group incorporates a forged carbon steel crankshaft, high-tensile connecting rods, and oil-cooled aluminum pistons. Engine geometry measures an 87 mm bore, 102.4 mm stroke, 21.5:1 compression ratio, 8.0-quart oil sump capacity, and dry net weight of 886 lbs inside its sound shield.

Key Features of Cummins QD 17MDKDP-8111A

Sportfishing yacht owners buy Cummins QD 17MDKDP-8111A generator packages to upgrade older auxiliary units inside tight machinery rooms. This 60 Hz single-phase package delivers clean 120/240-volt split-phase power to eliminate electrical interference across high-power chirping sonars.

• 17 kW continuous 120/240-volt single-phase power drives high-amperage sub-panels without line voltage drop.
• Four-pole brushless exciter alternator design eliminates commutator brush maintenance while stabilizing total harmonic distortion.
• Acoustic sound housing suppresses internal combustion noise down to 65 decibels at one meter distance.
• 17MDKDP-8111A marine generator electronic control board continuously monitors exhaust temp, oil pressure, and raw water flow.
• Cupronickel tube-and-shell heat exchanger shields internal cast iron block passages from direct raw seawater contact.
• Single-side service design clusters fluid dipsticks and spin-on filters behind one fast-release latching panel.
• Water-cooled cast iron exhaust elbow isolates extreme exhaust heat from composite yacht bulkheads.

Precision Alternator Frequency Output

Operating at an exact 1,800 RPM governing speed, this four-stroke diesel maintains stable North American 60 Hz current. Full electrical output yields 17 kW and 70.8 amps across 240-volt split-phase lines. Fuel burn records 1.30 gallons per hour at 50 percent load and 2.30 gallons per hour at maximum output. Internal oil galleries maintain 40 to 60 PSI hot pressure, safeguarding main bearings.

Bilge Mounting Envelope Dimensions

The compact sound shield measures 44.4 inches in length, 23.9 inches in width, and 26.6 inches in height. Heavy neoprene base mounts absorb secondary hull harmonics. Exhaust plumbing connects to a 2-inch water-injected exhaust elbow, while the front and starboard service panels demand six inches of clearance for lube maintenance.

Scheduled Service Safety Rules

Operate the fuel feed priming arm to evacuate air from diesel filter bowls before initial engine start. Maintain full expansion bottle coolant levels to prevent dry heat cycles. This marine unit is not engineered for raw sea water block cooling, open deck installations, or unvented gasoline holds.

• Extract factory run-in oil and renew full-flow filter elements after the initial 50 hours of operation.
• Check raw water pump impeller flexibility and clean fuel separator bowls every 250 running hours.
• Descale heat exchanger core tubes and thread in fresh zinc protection plugs every 12 months.
