Don't even bother looking, if you do find one, it can't stand today's ethanol fuel. Instead, use a Sierra 18-7208 float. It is made for Mercurys and is available right here at iboats. Remove the spring, and drill the center hole all the way through with a 3/32" drill. You can do further modification with a sharp knife or sandpaper. The foam is "closed cell" so cutting on it won't make it absorb fuel. http://www.iboats.com/mall/partfind...&gd_poid=112204&gd_row=1&**********=547612176
