This passed weekend while fishing. I noticed my motor wasn't running that well. Upon further inspection we discovered that water wasn't coming out the cooling hose. So we took the water pump cover and hose off to find that a Mud Wasp female had built her nest inside the hose while my boat sat on land during last week. After digging out the mud and the dead wasp larva. It all works fine again. Lucky I didn't blow the motor. Stupid wasps!!!!! Has anyone ever heard or seen this before.
The female mud wasp will build anywhere and I guess my water pump hose looked inviting to this wasp.
I will be checking this more often to make sure she doesn't do it again.

I hear about this all the time on this forum. Never had it personally happen but apparently it's common.
