1997 90 hp/Have had issues for a long time.What I think I found,the panel on boat has a choke switch as well as a key switch,Seperate switches.I found the blue choke/primer or what ever they call it wire, from the eng ,tied in to the yellow ,run circut.Well it was fried.But ,what I think I learned,is,this eng.should have a constant voltage,supplied from stator to heat a unit.thereby after warm ,the enrichment is removed.Now,Im thinking ,someone has wrongly tied the choke button on dash to a syste not designed to operate in that way.Any opinion ,greatly appreciated.
