tim: the 'classic', ie older, M17s have the cut-out transoms. these models all come from the VERY early 80s and earlier. these M17s also have the following in common - * cast iron centerboard * steel punchings for ballast in skeg keel * metal framed windows * the 'old' cockpit/deck mold ('streamlined forward cabin hatch that opens forward, cabin-top is shorter meaning less sitting headroom, cockpit seats are lower in relation to the cockpit floor, and the cockpit lockers have a different layout). * the transom to deck joint is prone to damage dave scobie M17 #375 - SWEET PEA visit SWEET PEA's www-site - http://www.m17-375.webs.com --- On Wed, 4/7/10, Timothy Erwin <sailtim@yahoo.com> wrote: I have been looking on the net all over for Montgomery 17's .I notice that some models have a cut out in the transom for an outboard in the transom. Other models have a motor mount on the transom. The cut out for the motor looks to make the most sense to me. I assume that the difference is the year model. If so, what year models have the outboard cut out in the transom? Thanks, Tim Erwin
