Re: Gamefisher model 217-585750
That 7.5 hp Eska-built outboard uses a Champion RJ12Y plug. Gap it at .030. I'm not sure of the fuel

il mix on that model. It uses a Chrysler-style fuel connection.
You can see exploded view diagrams and parts lists at
www.searspartsdirect.com by putting your model number in at the site. Some parts are available through Sears. Others can be obtained by calling the phone number at
www.certifiedpartscorp.com.
You can probably find a manual on ebay. Just search for Gamefisher 7.5 or Eska 7.5 there. There's a guy there who usually has the manuals.
You can find the year by going to
www.discount-marine-parts.com and choosing Sears or Gamefisher from the list.
Good luck with your outboard.
