- Engine displacement: 1.7L (103 cubic inches).
- Cylinders: In-line 4-cylinder.
- Valves: 16 valves, DOHC (dual overhead camshafts).
- Power output: 120 horsepower (crankshaft-rated) at 4,400 rpm.
- Fuel system: Direct injection with a Bosch VE pump.
- Cooling: Closed circuit cooling (heat exchanger) to reduce corrosion.
- Aspiration: Turbocharged and intercooled.
- Lightweight construction: The engine features a cast iron block and an alloy cylinder head. Its lighter weight, compared to petrol options of the time, helped to improve the planing efficiency of smaller boats.
- Efficient planing: The engine’s low-end power helped get boats onto a clean plane more quickly and maintain that plane at lower speeds, boosting fuel efficiency.
- Compact size: The D1.7L DTI is relatively compact, allowing for more space in the engine compartment.
- Emission compliance: With its turbo and intercooler, the engine met IMO (International Maritime Organization) diesel exhaust emission standards at the time.
- Reliability concerns: According to JustAnswer, the Cummins-Mercruiser 1.7L engines of this era have faced some reliability issues and reports of frequent failures, particularly in the fuel system and turbocharger.
- Manufacturer support: For repairs, some sources indicate that manufacturer support may be limited due to the age of the engines. Sourcing quality replacement parts can also be a challenge.
- Corrosion and mounting: The engines may be susceptible to corrosion and mounting alignment issues, which can affect the performance of the outdrive.
- Diesel noise: As with many direct-injected diesels, the engine can produce a distinct “rattle” at lower RPMs, though it tends to quiet down at higher speeds.
