Propulsion Controls

MI’selectronic engine throttle control system is reliable, robust, and easy tomaintain. We can provide multiple stations, complete with throttle handles,station transfer controls, and all equipment required to interface with yourmarine propulsion and/or thruster engines. Our propulsion systems can beprovided stand-alone or integrated with our other products, such astachometers, steering controls, and alarm systems.

Integrated Consoles

EMIhas provided customized consoles and panels for a large variety of marineapplications. Our designs are performed with 3D technology to better visualizethe finished product, prior to fabrication. Fabrication is then accomplishedusing precision waterjet and laser technology, to obtain highly accurate andclean surfaces that are ready for immediate assembly. High quality coatingsystems, to our spec or yours, provide a professional finish. We also installand pre-wire EMI or customer furnished equipment into our consoles.

Vessel Automation

EMI designsand manufactures automation solutions using state-of-the-art technology toprovide sophisticated control systems for remote machinery automation andmonitoring, power management systems, remote valve control and monitoring, etc.From simple pushbutton panels to complex programmable systems with touchscreeninterface panels, our engineers can provide solutions to meet and exceed yourrequirements and satisfy all regulatory concerns.

Steering Systems

EMIis a recognized leader in the design and manufacturing of workboat steeringsystems, gaining recognition for excellence and innovation in our designs. Ourflagship product line uses modern proportional hydraulic technology to providesmooth, precise rudder motion.
