I’ve got a 1998 242 cruiser and I’m having the same problem a lot of other owners are having with this model. I’ve read several old threads but in order to get an answer from another owner though I would start a new thread. The water is under the cabin floor by the shower box area. I can’t figure out where it’s coming from. I don’t have my water system on and don’t have a/c so it has to be another problem. Any other owners experiencing the same problem please chime in.
