    Pinging Chrysler Marine experts and owners re; raw water cooling system options!

    Is this the way the thermostat is suppose to look like? I thought mine was shot because it looks like it couldn't stop water because you can see right through it. Is that the way it is suppose to be? Thanks

    Should Water pour out or spray out of your exuast?

    Here is the bottom side of my pump. But I don't think it has room for 2 impellers. When I went to the parts store they gave me on that fit. Does this pump take 2 impellers? When we bought as far as I could tell, they only had one impeller in them and we changed them last year. Anyone have...
