ok reason im asking is im getting a TOPS fault code from the ecm and im almost 100% sure that there is no TOPS system in this year boat. I see no mercury switch ANYWHERE in the engine bay or anywhere else I can physically see. the boat will start and run and a minute later I get a long beep and check engine light comes on and the only code my candoopro shows is a p1200 blow by valve.
Nevermind we figured it out. Had a friend with buds and a megatech license come over and we rewrote the parameters in the ecm so it dont look for a TOPS that is not even there. Runs like a charm now.
