2012 240 Sundeck with digital throttle...

[Mike99]

2012 240 Sundeck with digital throttle and shift (DTS).  5.7 with Bravo 3.  Cruising last night and ended up getting towed.  When shifting from neutral to drive or reverse the engine RPM would increase but not engage the outdrive. Like running with Throttle Only. Right after shifting an alarm sounded.  Single steady beep for around 5 seconds.  No other issues.  Water psi, oil pressure, voltage, gear oil all in normal range.  No new alarm on the display.  The only pre-existing issue is an exhaust oxygen sensor.  Been working with the shop to resolve this for two years.  Thanks for any help.

Mike can you try disconnecting all fuses or batteries and wait 5 minutes and reconnect? Retry.

You might have a broken shift cable. That is a wire that connects from the throttle down the back of the engine and through the hull out to the outdrive. I've experienced a broken cable on my boat with DTS and with the cable broken, it merely becomes a digital throttle. The cable can be disconnected at the throttle end and pull the wire. If the wire can be pulled , it is either broken or disconnected at the drive. It shouldn't be able to be pulled. A cheap check to ensure that part of the system is intact, or.not.

As WickedRx indicated, the shift cable goes from the drive through the bell housing and transom, into the engine compartment to the top of my engine. There is a utube video on bravo 3 drive repair that shows how to repair/replace the shift cable. If it's broken, you can probably pull it on the engine side and it will probably pull the cable completely out.

Had something similar, it was the prop shaft.

Thanks for all the suggestions. Appreciate the help trying to figure it out. The issue turned out to be a failed shift actuator.

Thanks for commenting on the solution. It helps anyone else following the posting.

Two options. The more likely one is that the DTS shift actuator has failed. Second is the lower shift cable as mentioned above. Easy to diagnose. As the motor is running shift into gear while watching the actuator, if it is. It moving, it failed. If it is moving and the cable is moving with it at the actuator, likely the cable failed.

Edit above, “if NOT moving….”
