Overview
Custom built to MasterCraft's specifications, the RTP-1 5.7L delivers all the drivability advantages of multi-port fuel injection (MPFI) in a cost conscious power package. This is a solid power plant with all the juice needed from deepwater slalom starts to competitive wakeboarding.
Electronics are a key ingredient in any MPFI inboard system. The RTP-1 offers MasterCraft Cruise© (MasterCraft's privately labeled version of Indmar's ETC-electronic throttle and cruise-system). The Indmar developed system allows the helm throttle control to electronically connect to the engine's ECM. Throttle response is quick and smooth. The Electronic Throttle Control with Cruise feature is a bonus to recreational water-ski and wakeboard families.
RTP-1 uses Indmar's port injection system and 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.
Block hardware is what you would expect from a GM Vortec 5700. High-flow cylinder heads with straighter intake ports for more power and hydraulic roller lifters for reduced friction and improved performance.
The MasterCraft Power RTP-1 is protected by Indmar's 3-year limited warranty that covers fuel and electrical systems.
Certified: 3-Stars Ultra-Low Emission by California Air Resources Board 2007.
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.
