I have to ask what to me seems to me, a pretty bizarre question. Has anyone but me had a varmint of some kind ( mouse,rat, racoon, insert favorite here) in thier boat. I can hear whatever it is making a noise that sounds a lot like CHEWING, coming from in front of my v-drive. I have already put poison and glue traps everywhere I could. But this will drive me crazy. Just what kind of damage could be done?
