Shift interrupt switch?

Sounds like a bad lower shift cable, $75-100 for the kit. Use the genuine Mercruiser (Quicksilver) cable, it's worth the extra cost.

So its shot, versus needing adjustment?? Why does it work with the switch disconnected?? If the cable is shot I think it would just be shot and not work at all??

thanks

Read this previous post from a similar problem:

If you do the replace the shift cable, look at the shift shaft bushing/seal in the bellhousing while you are there. They have been redesigned better and are not that difficult to replace. When I did my cable the shift shaft seal inside the bushing was dry rotted and can allow water into areas that should not have it.

The shift interrupt switch IS working, that is why it dies. Either the shift cable is bad, or the shift shaft in the bellhousing is binding, or you have a drive problem.
The shift cable is the most common problem. And YES, you replace it, it's binding, and they don't just get out of adjustment. They wear out.

Do a search of this forum for "Shift Cable" and you will see what I mean.

Pulled the drive, a friend who has worked on boats for years checked it out and said it was bad......

also had water in the bellows..... so we are changing that.
