I would like to see that raw water cooled 470. Must be tricky with that aluminum block.

I just replaced head gasket, milled head, new valve springs, and a new outdrive
impeller pump. What temp should it run at....I have the themostat out
currently.
The dealer didn't have one and I didn't trust the old one.
Thanks
======================================
Assuming raw water cooled? In salt water, no more than 140 degrees F.,
in fresh water 160 to 180 is OK.
