Hi, just acquired boat at Chi. show after years of renting. 2005 Tracker 17WT. I have a few q's. Mostly to use n wisconsin lakes/flowages. I intend to keep for some time.<br /><br />1. It comes with low end Lowrance. I want to upgrade to gps unit. (I think) Is color worth it? Suggestions?<br /><br />2. I got Merc 90 (pre-optimax) Should i push for upgrade to Optimax.<br /><br />3. What is a good anchor system? Are the power ones worth it? I can live with crank, put power from the drivers seat seems cool.<br /><br />Thanks for any ideas.
