About the exhaust... Not to be offensive but do you know the difference between a water lift muffler and a standard exhaust?
A water lift muffler is a big canister that the exhaust is connected to, then a pipe goes through the hull at, or above the waterline. The muffler fills up with water coming from the (water cooled) exhaust system and the pressure of the exhaust gasses forces the contents out and overboard. The process continually repeating.
If the boat has a generator it will have a water lift muffler. The exhaust note is quieter and the water comes out the exhaust in spurts and dribbles (whooshes out intermittently).
The standard log style muffler is the near horizontal black pipe in your photos. Under that there is a vertical pipe that goes to the underwater exhaust fitting and a smaller pipe running from the end that goes to the above water side-exit exhausts.
Hope this helps.
