So I had a 2002 m155a2 on my boat but went bad found a m140a and put it on and used same harness, motor is in limp mode, I saw on another post say it’s because of the harness and they had to get 12v to the safety circuit but I have no clue what wire that would be if even that’s the issue? Any...
I have a 2002 Mercury 225hp, recently started my outboard and rev’s at like 3000rpm’s, this has never happened before just started overnight.. when I unplug the TPS it idles at normal range but as soon as I plug it back in it rev’s back up… So is it the TPS or could it be the computer?
Ive been seeing different ranges on these and it confusing,, I have a 2002 M115A2 on a 22ft pontoon whats the currect prop size or something that will get me close..
