Joe and Joel - thank you guys. Apologies, I was on "digest mode", so I didn't see your responses until now. I know it's engine coolant because as Joe said - "nothing else on the boat looks like it". Joel, I have a feeling you're right about the source. I think there was coolant in the aft part of my bilge - either it was spilled or the previous owner intentionally put it down there, and when it rains hard it's being pushed into the sump. If this is the case, I'm just surprised that it's retaining it's brilliant fluorescent green color after being watered diluted so much. It's very green. Looks the same as what's in the reservoir.
