Generator Exhaust Location?

Singleprop -- What kind of vessel are you speaking of for the exhaust redo? What problems do you have with the existing setup?

Be very careful designing and building*the setup FF describes. It may be a good way to get water back into* your engines creating all sorts of grief. The words FF used*may not apply in your case - "North Sea and Commercial."* Peruse boatdiesel and read about the myriad of presumably well designed exhaust systems that allowed water to flow downhill into the engines with predictable results.

It's not a redo - It's a new build "fishing boat". The exhausts are designed to avoid this problem.

Generator Exhaust Location?

Basically cooling water is introduced into the vertical part of the dry exhaust that goes down into the muffler, from there the mixture goes vertically up to the engine room ceiling, then forward and down (like a goose neck) to *a "T" where the two side exist connects.

That way - before a wave enters the engine - it will have to travel from the side exhaust exit into the T, then turn 90 degrees aft, then up into the goose neck under the ceiling, then down into the muffler, then a 180 degree turn up into the dry exhaust under the ceiling, then 90 degree horizontal and then finally another 90 degree turn down to the engine. And this is while the engine is producing gasses that pushes against the incomming water.

Can water enter the exhaust with this set-up?
