Please sir:<br />I am looking for a well informed person on outboard motors.<br />My 140 johnson developed a knock and I am debating "should I have it rebuilt or buy a used engine".I am retired and on a fixed income so I have a few questions.On my 140 it would take $20.00 a day to be out fishing.I like to fish every day or 5 days a week and stay home the weekend.What engine do you recomend?Is there a place where a guy can purchase an engine and pay monthly? mean while what is your opinion of a 1968 125 hp merc?The johnson rebuild is around 1600.00.Please advise<br /> Your Friend<br /> Danner
