Get the 13.5 "Scotty pump.  Look for the stainless steel shaft, as this won't break on you like a plastic shaft could.
You may find it rebadged as another name on the floaty part.  The stainless shaft give it away that it's Scotty, as well as Scotty embossed right on it. 

+1 on the Scotty.  Never had any issues with mine in 3 years.

thanks guys thats the one I will order .
