Hello, I have just joined this discussion group and this is my first post. Â I live in Winnipeg, Manitoba, Canada and sail on Lake Winnipeg which is the worlds 10th largest freshwater lake and is 264 miles long and 20-30 miles wide. Â My current boat, a 12Ft Tumbleweed, keeps me pretty close to home port so I am loking for a larger boat to extend my horizons. After much research I have concluded that an M17 fits my requirements. I have found several for sale in Minnesota and Wisconsen that are from the late 70s. I have noticed that some of the boats have the outboard mounted directly on the transom and others require a motor mount. Does anyone know if the transom mount with its cutout was specific to a particular year of manufacture. Also has anyone had experience with this model. I was wondering how succeptable this style is to taking on water over the stern. Â Thanks for your replies.
