I have what you are looking for - a one man fishing boat. 1994 14 ft Alumacraft with a 2004 8hp Nissan motor and 2004 trailer. It will take you away from your problems and to the fish. If it wer'nt for a pending divorce, I would never consider selling. I'm in Tampa and around the $900.00 range.
I have a mid 70's 20hp Merc that the motor mount tabs are cast into the block and snapped. I was told by a local welding shop that they could repair it, however I used the problem as a reason to get a 25hp. So if you want, it is yours for the pickup. It ran good to the point that they snapped, and still ran just could not pull start it anymore as the mounts hold the upper cowl with pullstart on. Pair that with makin moves rig and you should be good to go way under budget.
