2015 Mercury 90hp 4 Stroke ECM 8M0083209.


I purchased a new ECM under the advice of a local boat mechanic. When that did not fix the issue, and $2500 dollars later, a Mercury certified mechanic informed me the original ECM was perfect and the alternator I purchased off Amazon was the issue.


So since I had opened the ECM, I am unable to return it. I kept the new ECM and this is my original ECM. This ECM has around 200hrs on it. Gave me no issues and has been checked by a certified Mercury mechanic. Any other questions, let me know.



SIDE NOTE: Don't by Amazon's Alternators and Use Certified Mercury Machanics.
