scragman - 2/20/2009 11:01 AM For the second time now, I need to replace the Engine Control Module (ECU) on my Yamaha 115f 4-stroke outboard. Anybody else having such luck and where might I find a reasonably priced one?
What year? Whats the diagnosis?
In all the years, I have only replaced one ECM on a EFI 4-stroke Yamaha. And that engine still ran, but kept throwing a shift switch error. It had no effect on the engines running, but it was a USCG engine and they are fastidious type customers....... if you know what I mean.
