2002 240 Horizon 350 Bravo III 245 hrs.
Went for an evening cruise and after running out onto lake, could not return throttle control into neutral from forward idle position. Turned engine off and attempted to determine problem. Disconnected helm cable end on top of engine and was unable to move intermediate cable at all! Props only spin one way (forward rotation). Of course engine would not start and had to be towed in at midnight. Any suggestions (frozen cable, shift linkage or shift dog malfunction)? I already know it won't be cheap but need to get engine running before winter layup. We Love our Four
Winns. Please help.

Howdy,
Well it's not a Shift dog problem since the Bravo doesn't use "dogs" It's a cone clutch which is usually FAR easier to get into and out of gear.....
At first "look" it sounds like a simple shift cable malfunction or malfunction at the shift plate (bolted to your stbd riser/elbow)
It also may have pulled out at the drive etc... (the cable has a small aluminum "knob" at the end where it goes into the drive.
The drive has to come off to inspect. (it should come off anyway to look at the bellows etc..)
If the shift linkage inside the drive is frozen, you have much bigger problems that might require disassembly.
Are you wanting to do the inspection yourself? If so you probably need to get an OEM service manual. (#11)

See "Drive Unit In Gear, Will Not Shift Out Of Gear"
It will give you somewhere to start.
