1977 1150 Mercury in line 6

Motor started and ran fine all last year. Was starting and running fine when winterized in October, 2018. Got it out to go fishing yesterday. Cranks over fine, but never fires. Checked spark at plugs and coming out of coil. It is sparking, but it appears to be sparking every plug continuously. All plugs are new and getting fuel to carbs for sure.
