With phenomenal acceleration and outstanding performance the C18 proves to be a top competitor in the 1000 brake horsepower class.
The new C18 propulsion engine has 25% more power, faster acceleration than the 3406E, and has an excellent power-to-weight ratio of 1.56 kg per metric horsepower or 3.49 lbs per brake horsepower. Even though the C18 has a slightly larger package it weighs approximately the same as the 3406E.
The ADEM III electronic control system provides engine speed governing, automatic air/fuel ratio control, engine parameter monitoring, and system diagnostics, as well as cold start strategy, engine synchronization, trolling mode strategy, and slow vessel mode. The C18 has a 70-pin customer connector compatible with the optional display systems – Marine Power Display, Marine Analog Power Display, and Engine Vision. C18 is also compatible with the Multi- Station Control System when available.
With a 25% increase in power at approximately the same weight of the 3406E, the C18 engine has an outstanding power-to-weight ratio of 1.56 kg per metric horsepower or 3.49 lbs per brake horsepower.
The larger bore and stroke give the C18 24% greater displacement from a slightly larger package size than the 3406E.
Higher flow fuel injectors provide more fuel for combustion and in turn produce more power.
The two smaller turbochargers require less inertia to engage and thus provide more boost at lower engine speeds.
This additional power provides quicker acceleration and allows the vessel to come up on plane faster.
The C18 engine has seawater aftercooling (SWAC) which also contributes to greater power output. The titanium plate heat exchanger incorporates the expansion tank, deaerators, thermostats, shunt line and crossover pipe providing a compact design.
The design of the camshaft helps the engine develop higher injection pressures for lower smoke levels. The closed crankcase ventilation system removes oil vapor from the engine room.
High quality white urethane paint is standard with an optional superior quality
