Yanmar Key Switch problem

We have a Yanmar Diesel on our Pearson 303. Yesterday while the motor was on the key fell out (engine was still running), and now we can't get the key to go back in. It is in the on position so that is not a problem, we can still turn the engine off by pulling the stop lever or killing the battery. Has anyone else had this problem? Is it fixable or should we get a new switch for $50.....

Thanks

Replace with a key switch that has tinned and bronze components. The stock Yanmar key switch has brass and untinned components and really shouldnt be used in a 'marine environment'.

A few shots of WD40, etc. will help to loosen the frozen tumblers in the OEM Yanmar key switch.

Thanks for the quick replies. I've never had a problem with the key or tumblers in the past, and the key was in fine but must have been kicked or knocked out.

Before you buy a new switch, try and turn just the outer cover with the key slot. It may have moved and is no longer aligned with the internal slot to the tumbler. By the way, these keys/tumblers are very simple. I forgot our key at home a few weeks ago and was able to easily turn the ignition by using a padlock key of roughly the same size and wiggling it around a bit in the slot. To shut it off I didn't even need to insert the key all the way.

Re: Yanmar Key Switch problem

I just attempted to install a new key switch today, but as soon as I try to connect the alarm connection, it starts sounding and will not stop. This was not an issue before replacing the key switch, and the boat has not been started or moved before or after the replacement. Any suggestions?
