Hammers, It depends what sort of boat you want.....If you just want one that you can pull in and out every day with an outboard motor try the place in Bodrum opposite Kipa --- not cheap but you only need a fibre glass hull --no motor. There is also a place on the left hand side on the road to Bodrum just past the cement station as you come into Ortakent. They'll even make a hull for you there.
Once you've bought the hull you can pick up a new four stroke Yamaha or Honda 9hp outboard for a little over a thousand euros. Gazarra
