but since you are living in New England and might be just getting on the water again, thought I would throw this out - if you haven't bought a mount yet, don't. You'll save money and have a better mount by making your own mount. I made mine by bolting two pieces of aluminum angle iron to the insides of my canoe, opposite each other behind the rear seat, just below the gunwales. Then I took a 2X4 made of pressure treated pine and cut it to fit to span the canoe back there. I took two pieces of the thickest finishing plywood I would find and glued them together to make a double-thickness. I then bolted that into the 2x4 (bolts going all the way through 2x4 with washers and locknuts), perpendicular, as the place to attach the motor. I then drilled holes in the ends of the 2 x 4 as places to pass through the bolts for holding the mount to the angle iron, and I slathered the mount with 4 coats of marine varnish. 4 years later, it looks like new. I can send you detailed pictures and a drawing to help you assemble it if you like.
