Thoughts on selling boats

From my experience selling boats, most buyers want a "ready to run" boat.
I think it would be harder to sell it in the spring without a motor...most people that get the bug to go boating want to go "now" and not have to rig an engine on their new toy.
 
Also, a serious buyer might want to go for a test ride.
 
Another option would be to locate another engine...say 50 horse or so...and let the buyer know that you can lay your hands on bigger power to put on it in short time.

I agree with both of these guys.  You'll be able to sell your toon much sooner with a motor on it.  Without, I would imagine you'd get many window shoppers, taking up your weekends to show and not sell.  You figure that they would need to buy it, then look for a good deal on a nice motor.  Meanwhile looking at other full package toons.
 
I'd say sell as a package and list for $500 more than you think you'd get.  If it sells for that price, put that in on a new (or gently used if you could find) 20HP.  If you have to knock that $500 off and an additional $500, then you are in the used 20HP market or 15 or 9.9.  Might as well shoot for what you want and see if that 20HP pushes you as fast as you want to go.  I doubt that it could be your only Erie motor, but might get you barging at 10mph on Artie, rather than barging at 7mph...  If 4 stroke and you get into trolling, you won't be sucking exhaust fumes.
