I have a 1991 OMC Cobra 5.7 liter (350 Chevy).<br />It ran well all weekend. Suddenly it will not turnover. Like a dead battery , but the battery is hot. Is there some kind of by-pass or interrupt switch that will keep it from turning over? What are the switches mounted on the shift cable next...
Can someone tell me if Synthetic Oil is ok in a 1991 OMC Cobra 5.7 (Chevy 350) Crankcase? 10W-40, 20W-50? And, How about Synthetic Lower unit Oils and Greases? I am in SE Texas where it's Hot. Synthetics seem to take the heat better. Thanks,
