Why not run a heated O2 sensor?.  Just takes 12V, or are there
other considerations?

The exhaust manifolds and risers are water cooled, i.e. double walled with 
cooling passages.  I could replace one riser with a non-cooled piece, take 
the water from the manifold and bypass it downstream, but I think I can get 
the results I'm after by careful tuning.  I would argue that a marine 
engine is easier to tune than an auto since load doesn't vary much (you 
don't go up hills too often while on the water.)    Feel free to poke holes 
 (but not in the boat, please)
