Re: what is it?
I think you're right on the year. H is the eighth letter and three making 83.
West Bend became Chrysler in the mid sixties became Force by US Marine in the mid eighties became Force by Mercury in the early nineties and died at the end of 1999. I think they were something else before West Bend. Memory is failing. Some Sears and Wards motors were made by Chrysler/Force. Not sure of any others. tcoutboard.com or eBay for a hood.
Oh yeah, they started life as Kissel outboards. They also made cars.
