This is a 4 cylinder 1985 50 hp. It fires and runs on cylinders 1&3 and does not fire on 2&4. Has new spark plugs. coils are on order. It had a bad rectifier which has been replaced but we have not tried to run it since. We are waiting for the new coils. Afraid we would destroy the new rectifier. What else could cause this problem.
