    Thinking of doing water impeller....Anything to watch for?

    My impeller needs done on my 1988 150 merc black max. I would like to save money and do it myself. I am mechaically inclined, as i know how to do almost anything to a car/truck.

    To winterize, or not to winterize????

    Im trying to figure out what would be best for me... I have a 1988 black max 150 just got it 3 weeks ago. Previous owner always fogged the engine/winterized in the fall.

    Can you put a kicker on fiberglass bass boats?

    I got a 1988 basstracker 18' fiberglass boat. My buddy said he has a newer 9.9 hp engine he would sell me for a kicker. Reason is i do alot of trolling and have a 150 v6 black max and it sucks up the gas. A kicker would pay for itself in a few months. Is there anyway I can mount this to my boat...
