This is my first post on the site. I have been reading a lot and finally decided to post a question. I have a 16 foot skiff with 2000 mercury 50HP that I just bought from a neighbor. To make a long story short the neighbor got the boat when he bought the house from two little old ladies who had bought the boat new in 2000. He has owned it for 3 or 4 months and has not done a thing to it. The boat fires up fine and seems to run OK. Now that I am the new owner I would like to get the boat up to speed with its maintenance and start keeping records of what is done to it. The marina wanted 500 to do a tune up but I think I have worked with enough engines that I am going to tackle this one my self. From my reading I gather that I need to change the gear lube and make sure the seals are good. I have also read that I need to change the zincs and maybe the fuel filter/plugs. What else can I do to get this boat in shape for the fishing season? The marina was saying replace the impeller and adjusts the carbs and check lines for tightness. Any help would me great.<br /><br />Thanks
