"Jeff, do you have a model number. Sea King, which was Montgomery Wards "store brand" was built by a number of companies over the years. And while I suspect your motor is actually a Chrysler, the model number will confirm that.
In most cases any motor can be converted to electric start, but often the cost can be quite high (sometimes upwards of 1000 bucks). But with a bit of looking and scrounging around sometimes considerably cheaper. At the bottom end you could count on (realistically) at least 300 bucks plus the cost of the battery."
