OK, so engine temp seems normal, correct?  It could be nothing more than the hot summer temps we are enduring now, especially if water flow seems normal.  The exhaust housing gets real hot though, correct?  Does kind of sound like the issue we uncovered with your 10hp, there is that little bleed hole on the bottom cylinder’s cooling passage that is supposed to cool the exhaust housing.  But, you mentioned the block was dipped/tanked, so you would think that would have gotten cleaned, but you never know.  I wish I had one of those blocks to help locate that hole for you, do you still have the original block for investigation?  Normally, I would say this is no big deal, except I don’t want your beautiful paint job getting ruined on the exhaust housing.   I guess I might try running the engine at night, or early morning before it gets too hot out to see how it behaves then before getting to concerned.
