Fogging and Winterizing an EFI Single Throttle-body Four-Stroke Outboard Engine

If you have an EFI single throttle-body four-stroke outboard like the Yamaha in-line-four F175, the fogging and winterizing process is a bit different. Tune in, to learn how it goes. EFI single throttle-body four-stroke outboards (like the Yamaha F200 and F175), require a slightly different fogging and winterizing procedure than many other types of outboards. Unlike carbureted engines you can’t simply spray fogging fluid in via the air intake, because the oil is too thick to effectively make its way through the fuel system.
