Re: Sears Gamefisher - Made in Canada Info Needed!
I have a 14' Sears Gamefisher that is somewhat similar in appearance (it has only 3 bench seats, unlike the 4 shown in your pic). The plate on the transom says it was made by Harber Mfg in Canada, which I take it was the old Harbercraft plant in Niagra (Harbercraft, as far as I can tell, now only exists in Vernon BC).
I don't think it's worth much - a few hundred at best. I bought mine 25 years ago when I was much younger and less knowledgeable about boats. It's cheaply made and rides poorly (the bow tends to plow through the water no matter how trimmed) and I use it only as an extra boat when needed. I'd get rid of it and go buy a Lund; you'll be much happier. Sorry for the less than helpful news.
