I recently purchased a Balboa 16 sailboat. She displaces 1000 lbs and drafts 25' with a shoal keel. I'll keep it in a marina in the central Puget Sound area. The boat didn't come with an outboard, which brings me to my question. I need a motor to get this little boat in and out of the marina...and maybe bail me out of trouble from the 3-4 knot ebb/flood tides that are common in Puget Sound. I have been told that a 3.5hp would be adequate...I am leaning toward a Merc 3.5hp. It goes 40lbs compared to the 55lbs of the 4 & 5hp motors. Anyone like to weigh in on the adequacy of the 3.5?
