Hey Worldworstfisherman bought a little 14ft jon boat with a 7.5hp mercury outboard. Well we tore it down to replace some seals and the water pump and when we took the prop off we found that the part that holds the prop shaft seal was busted big time. When WWF was trying to get it all taken apart he knocked a chip out of the foot housing where it butts up to the prop. Does anyone out there know of any place we can start looking for a lower unit. Its a strong running motor, he hates the thought off trashing it. He was thinking of maybe just trying to sell the whole pkg boat, motor and trailer.
