Hello - I own a 2011 Tracker Tahoe I/O Q8SSi. Very low boat/engine hours. Boat was winterized last Fall by Bass Pro - and they replaced the trim kit for $2K (ouch) - they supposedly fixed a beeping sound but it has come back this spring. I get the normal alarm sound when first starting. Then, about every three minutes, I get a short beep, maybe for 2-4 seconds, then it goes away. Three minutes later the same sound. Oil appears fine. Tran fluid looks good. Beep even sounds when Master Switch is off. Any idea of what may be causing this unpleasant beeping sound?
