My first

Chance,
Glad you got things going.
I can't help but add, I may be of the extreme, but I pull the raw water system apart every year, including manifolds, risers and inspect the cooler inlets. The manifolds and risers get looked at and re-painted and the pump gets pulled and impeller replaced every other year.
The cooling system is probably the most important and can get clogged or corrosion can take over quickly. The fuel system is probably next in line.
Anyway, you probably learned some things and thanks to the help of Miles, you got through it.
