gear

I have a 2008 Sea Ray 270 SLX with the Mercruiser 496 Mag. I have the DTS throttle and shifter. The throttle works but the shifter does not engage to put in gear. I have checked the DTS fuse and replaced the battery and still no go. Any experience with a solution to this problem?

I have a Bravo III that's stuck in forward gear. Attempts to use throttle only from the control arm at the helm didn't work. The boat still lunges forward. I disconnected both lower and upper shift cables. Upper moves, but the lower is stuck. I removed the drive, and the lower cable moves...
