Starting to see corrosion.

I spray the outside of the pumps and nozzles with white lithium grease I also spray the engine and all the electronics never have any issues. I rinse my engines with car wash soap that has wax in it to coat the inside of the water jackets .

Hey that’s great news! Some time and elbow grease and all will be right!

I was doing some research on the anodes today, thanks @Jim_in_Delaware, and was reminded of something I had read a while ago. When you see the anode on the rear start to get crusty, give it a light cleaning with a fine bristle stainless wire brush to keep its performance up. I also was told that the anodes on our boats are most likely a blend of zinc, aluminum, and magnesium to make sure they work over a variety of conditions.

I also spoke with my marine mechanic friend about how to flush fresh water minerals out of the block. He told me how they used to use a muriatic acid solution on the big sport fishing boats to dissolve barnacles that had grown in the fresh water to sea water heat exchangers. The muriatic acid would dissolve the shells since they’re calcium based. I asked him whether I should consider doing something like that to my boat, he said no, as there are no heating issues with my boat, and a flush like the one mentioned is hard on things.
