I just bought a 2007 saltwater edition E-tec new in the box from a dealer. 3 year warrenty included. Comes with prop, controls, wire harness, cables. My brother and I will be installing it on my boat, then we have to take it to a E-tec dealer to have it dialed in. I have heard stuff about computer up dates, what should I be aware of when talking to the dealer? We will be running the evinrude 100 something synthetic oil. I heard about having motor set up for that. What kind of problems have they had with the 2007. any concerns that I should be aware of. Puting on a 24 foot lone star that we completely re done into a center console. we have a fuel water seperator. sub floor 38 gal gas tank. has oil gas mixture for last engine in it. we will be pumping out gas mixture and flushing a couple of times with more unmixed gas. Is this enough? Tryed to google for Tach and warning gage. hard to find. where can I pick these items up and what should I expect to spend for them. Did I miss anything? Thanks in advance. Dan
