Mercury Diesel TDI 4.2

Mercury Diesel TDI 4.2

Mercury Diesel TDI 4.2 - Mercury Diesel TDI engines provide an automotive-like quality and reliability and are backed by Mercury's ultimate global service network. Exceptional torque at low engine speeds provides excellent acceleration and a reduction in time to plane. Mercury's TDI engines are lightweight, compact and lead the industry in horsepower to weight ratio.

Engine Overview

• Unmatched performance from an engine that powers exclusive, power-oriented vehicles like the AUDI® Q7® and A8® packaged in a propulsion system designed specifically for marine applications
• Excellent acceleration enabled by exceptional torque at low engine speeds reduces time to plane
• Fuel savings versus gasoline options will approach 50 percent in many cases, extending range correspondingly
• High power engine allows replacement of big block gasoline V-8 without sacrifice in acceleration or top speed
• Peace of mind is delivered by the Mercury global service network
• Industry-leading horsepower to weight ratio


Fuel System: TDI technology with common rail fuel injection system provides precise fuel control, nearly eliminating the traditional noisy sound associated with diesels, producing exceptional fuel economy and nearly no smoke or smell.
Electrical System: 12 Volt Alternator: 120 A
Coolant System: Thermostatically controlled, closed coolant engine, providing the ultimate in engine corrosion resistance, complete waterjacketed turbo chargers and exhaust system, reducing excessive engine compartment temperatures, water-cooled engine oil, gear oil and
steering fluid, if applicable, extending the life of these systems.
Emissions: EPA Tier 2, IMO Tier II, and RCD certified

Available Accessories

Instrumentation: Analog gauges provide data on engine speed, oil pressure, battery voltage and coolant temperature. Drive trim for sterndrive applications.
Drive Capability: TDI 4.2 is available with Bravo One, Bravo Two and Bravo Three XR sterndrives or ZF inboard transmissions.
