I have a 1984 35hp mercury.  I am wanting to try to find a jet lower unit for it cause im planning on doing some shallow water fishing in some rivers.  Does anyone know how much it would cost me to get something like this and where I could get it??

Thanks!!

Because we have so many shallow streams, we're sort of the jet boat capital, so I'd probably elect to go to Troutt and Sons near St. James, MO. They can be found with a simple search, but I'd vernture a guess of around $1200 to convert.  Then you might recoup some $ if your sell your original lower unit.
