drawbar

I am planning on buying jetski this spring and I was wondering what size drawbar you purchased to pull a single jetski trailer so that it is level? I have the 1 1/4 hitch. What size ball do I need for a jetski trailer? Thanks for your help.

Hi I have an 07 ex-l that came with the oem 1 1/4" hitch installed, but when I bought the crv I never recieved the drawbar for the hitch. Does anyone know the drop/rise required for the honda hitch? thanks
