Called Tracker about the screens and they could not tell me for sure if there are screens on the intakes or not. Looked at the owners manual and it showed screens on all three systems which are installed in Tracker boats but was told that those are just generic manuals, not for any specific boat. I agreed but what other livewell systems are installed on Trackers? I cannot believe that Tracker can't tell me about the parts on one or more of their boats. Anyway, it's not that big of a deal, I'll just buy a couple of screens if they are not supplied and do the minor refitting to adapt them. Just kind of poor customer service if your employees don't know your product well enough to discuss. From my experience with my 175, I would not use the livewell without screens.
