The ad vanced com bus tion system min i miz es noxious exhaust emissions and en hanc es over all enjoyment of boat ing. EVC/MC – Plug and go (option)
EVC Electronic Vessel Control is the lat-est development in instrumentation for marine engines. It offers a higher level of integration with your boat: speed, tank level, depth and surface water temp as well as an optional trip computer inte- grated into a uniform instrumentation. EVC makes boating easier offering new software options such as power trim as- sistant, a function that adjusts the power trim depending on engine rpm. EVC is scalable from a classic dashboard up to advanced driver information systems. The system is built on the latest automotive technology with waterproof connectors, so it’s just plug and go.
