Thanks - I'll do that. I also think there are brass drain plugs on the exhaust manifolds. If so I'll do the same there.

Draining engine and manifolds of water
If I remove the petcocks from the engine block, will that also drain the water from the exhaust manifolds or will I need to detach the hoses for those to drain? Engine is a Merc 888. Thanks

I'll jump ahead - if they do show hot, what is the cause? The manifolds and risers aren't very old, not many hours (under 100), and only in fresh water. Would the water circulating pump on the...
