I am looking at a boat with a Mercruiser 350 Mag MPI. The boat is a 2001. Owner states the Hourmeter went out last season.
I called a Mercruiser dealership and they stated that they can get RPM profiles from the ECM, but NOT total engine run time. This dealer mainly deald with outboards, so maybe different system on inboard. Has anyone with this engne got hours off the ECM from their service shop??
