Green stuff from water leaks?

I am getting set for a haul out and in advance of my trip to the Abaco Islands in April. I've been off the boat for some time and when I started to work on clean up I found all these green corrosion telltales. Looks like slow leaks over time. Around water pump and Heat Exchanger ends and fittings.
Any suggestions?
Thanks again,
Jamie

There are rubber o-ring gaskets on each side of the heat exchanger. Time to replace them!
Also, a good opportunity to clear out the exchanger ports.

I've ordered the replacement gaskets and the new covers, etc. Let's see if that fixes the problem.
Thanks for the reply

Jamie,
Electrolysis substantially increases the corrosion/oxidation.
Check for both AC and DC current-- one probe on the engine component, the other on something in the water. Just dangle one end of a wire (strip an inch or so) in the water and bring the other end to the engine so you can use your meter there.
