Hey guys or gals....Trying to save a little money getting ready for the boating season this year. I was wanting to do a basic tune up on my engine....plugs, wires, dist cap, oil change....<br /><br />What else should I do?<br /><br />How much of this can I get at Autozone compared to going to a boat dealer?<br /><br />Starts good with a little throttle, idles a little rough. Dies sometimes when you let off the throttle to quick. Takes a couple seconds to get up and go (sometimes backfires) any suggestions?<br /><br />1992 Glassport/180 Euro w/ 5.0 mercruiser.<br /><br />Thanks.
