My new-to-me M17 did not come with a motor. It did, however, come with a big honking scissor-type motor mount hanging off the transom. Because it is a 1976, it also has the transom cut-out motor mount. The motor of my dreams is the Tohatsu/Nissan 4 stroke 4hp. It is available in short (15") and long (20") shaft. My question is, will the long shaft work reasonably well if it is mounted in the transom cut-out, or should I plan on using the scissor mount either way? I would also be interested to hear whether the Tohatsu/Nissan 6hp "Sailpro" (25" shaft) works well with the transom cut-out. There are other reasons why I probably would not buy one of those but, if meant getting rid of the scissor mount, I would at least give it some thought. Thanks
