Interfacing Yamaha F-150 to a70d MDF

[Chuck - Raymarine - Moderator]

pacsport220,

It doesn't take much searching of the Internet to come across posts indicating how some deviated from the recommended and supported methods of product installation. Some meet with a degree of success, while many others do not. The problem with such deviations from the recommended / supported methods of product installation is that they more often than not, such deviations have adverse effects upon performance, and/or product life, and/or installation materials. As indicated within the referenced FAQs, engine gateways are required by Raymarine to ensure proper isolation (both for electrical and communications purposes) between engine systems and marine electronics systems. In the end, the decision to deviate from recommended and supported methods of product installation may be made by the installer, but at the risk of product warranty, product performance, and product life.

The shortcut which you have specified would be considered to be an unsupported method of interfacing an engine to an MFD.
