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
• High power engine allows replacement of big block
gasoline V-8 without sacrifice in acceleration or top
• 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.
