TOPIC: McCulloch 13' Sport

Several years ago I found a McCulloch boat/33 hp Johnson motor and trailer sitting in a parking lot with junk/weeds growing out of it. Long story short, I bought it as a retirement project and ....the time is here. The manufacturer plate says it is a Made in Canada McCulloch 13' Sport. I've looked all over and can find lots of information about McCulloch chainsaws and generators but NOTHING regarding this boat! I know he had a partnership with Scott Atwater but can find nothing about McCulloch boats independently. His office was in Rexdale/Toronto but that's all I know. If anyone can fill in some blanks I would appreciate knowing more about my "parking lot project !" Thank you
