I have a 2008 Tahoe Q5 with a Mercruiser 4.3 I/O. The first few times I took it out, everything was fine. Last week, it was going dead when I put it in gear. Since it's under warranty, I took it into the shop and they told me it was the shift interrupter switch. They (Tracker Marine) told me it was sticking and that they repaired it. The next time I took it out It had the same problem. From my research online, this sounds more like the cable than the switch itself. Any ideas?
