i recommend a long-shaft outboard. i used a long-shaft honda 2HP on my M15 and still would cavitate the prop when moving forward of the cockpit-to-cabin bulkhead. on my M17 i also can cavitate the long-shaft outboard if the seas are greater than 6-inches and i go forward of the mast. - Dave Scobie - M17 #375 - SWEET PEA - www.m17-375.webs.com - former M15 owner - Sage Marine - www.sagemarine.us --- On Mon, 2/21/11, Martha Ekwurtzel <marthaekwurtzel@aol.com> wrote: I wish I had a short shaft for my M 15 motor mount. It is obvious from the specs listed in the motor owner's manual the prop extends several inches too far beyond the bottom of the transom when the mount is in the down position. Perhaps it's a matter of the hieght of the initial positioning of the mount on the transom? Martha Ekwurtzel M 15 "knot head" Lake Koshkonong, WI John Tyner <tynerjr@md.metrocast.net> wrote:
Thank you, Connie. Now was that rectangular hatch in the actual seat (horizontal) or the vertical inner wall aft of the seat?
I'm also using the Honda 2 HP, but long shaft (I think).
