I've seen some commercial boats with an engine air intake snorkels above the pilothouse. One guy I watch on youtube bought a commercial boat to use for a hobby business and it has one. I thought these were just simple engine room air intakes, but they are piped directly into the air filter housing. This makes the air intake a sealed duct.
The only reasons I could come up with for this is 1)cooler intake air for better performance or 2)the ability for the engine to run submerged in water. The first I could understand on a commercial rig that may run for days, weeks, months, non stop. The second seems like overkill. If my engine is in the drink, I'm probably, or hopefully, in the life raft along with the crew and the EPIRB.
Is there any other valid reason commercial or pleasure boat wise to have an engine air intake piped above the pilothouse? I can't see a valid reason for a pleasure boat but commercial outfits are a whole different animal that I'm sure I don't completely understand.
