Overview
MasterCraft's MCX is the most powerful 5.7L engine in the MasterCraft Power by Indmar lineup. It's metallic red, high-styled plenum and valve covers are unique.
MCX is derived from GM's classic Vortec 5700 and features Indmar's custom high-performance multi-port fuel injection (MPFI) intake manifold with longer, more efficient runners to deliver stronger-than-ever bottom to mid-range torque. It's brain is Delphi's most advanced water resistant ECM (Electronic Control Module) the MEFI-5 hardware/software system. The MEFI-5 system is custom calibrated by Indmar to provide maximum performance and drive ability. By custom calibrating the ECM to match hull design requirements and the intended boat application this process allows boat and motor to perform as one seamless unit. The three-dimensional system precisely manages fuel, ignition and air. It is programmed to deliver the power skiers' and wake boarders' need, plus the classic turnkey starts, unhesitating dependability and fuel efficiency that only Indmar can deliver.
New to the 2007 MCX is the patented one-piece ETX/CAT (Extreme Tuned Exhaust with Catalyst). The most dramatic achievement for boater safety is ETX/CAT's substantial reduction of Carbon Monoxide (CO) gases in all part-throttle operating modes. Neither the California Air Resources Board (CARB) nor the Environmental Protection Agency (EPA) currently regulates CO emissions, but when they do Indmar is ready to meet or surpass those regulations.
There is no measurable engine power loss thanks to ETX/CAT's extreme tuned manifold/catalyst design. The ETX/CAT system is a free breathing, header style performance exhaust manifold designed to incorporate the catalytic converter as a compact assembly.
Certified: 4-Stars Super Ultra-Low Emission by California Air Resources Board 2007.
The MCX delivers awesome torque perfectly placed to provide the exact power-band skiers and riders need.
This custom Indmar inboard is privately labeled as MasterCraft Power's 5.7L MCX. Like all Indmar designed engines, it carries a three-year factory-backed limited warranty that includes fuel and electrical systems... the industry's finest.
The Indmar ETC (electronic throttle and cruise) system is privately labeled and marketed as MasterCraft Cruise©. The Indmar developed system allows helm throttle control to electronically connect to the engine's ECM. The throttle response is quick and smooth. The Electronic Throttle Control with Cruise feature is a bonus to water-skiing and wakeboarding families.
Outstanding performance and durability, all backed by Indmar's exclusive 3-year limited warranty, which includes both fuel and electrical systems.
Note: All MasterCraft Models are available as Salt Water Specific engines.
Experienced saltwater boaters will be the first to appreciate the extensive list of saltwater-specific details found in the MasterCraft SS series. All marinized parts are E-coated, an advanced electro-coat dip process that provides optimum protection against corrosion. Unlike paints or powder coating, E-coating completely covers both external and internal surfaces, creating a permanent-paint-to-metal bond. Will not peel. Will not crack. Corrosion will not put a dent in it.
SS Cooling systems are totally closed and corrosion free. Saltwater never enters an SS engine system. It uses only propylene-glycol/water coolant driven by a high-flow pump. Coolant tanks are easily accessible for filling and maintenance and are equipped with sacrificial anodes for extended life.
Each MasterCraft SS engine is protected by the same three-year limited warranty that backs every OEM installed MasterCraft engine.
