Routing the exhaust through the tower of a boat

Abstract

An exhaust system on a boat can be dangerous if the exhaust is not plumed properly through the boat. If a boat has a tower on it the exhaust can be plumed through it. The tower will be made to accept the exhaust gasses. The tower will still look the same except there will be tips sticking up on each side of the tower where the exhaust will escape.

1 . To safely get the exhaust away from the boat, the exhaust will be routed through the tower of the boat; from the motor the exhaust will go to a tank that separates water and exhaust; the exhaust will go through a muffler where the exhaust will be separated with 2 ports coming out of the muffler; two exhaust ports will be plumbed through the boat on the port side and starboard side where the tower mounts; normally around the center of the boat on the top of the side walls is where the tower mounts; a 3 to 4 inch hole we be cut in the top of the side walls so the exhaust can be further plumbed into the tower; a cover can be installed with a 3 to 4 inch hole in it and screwed to the boat, this will give a place for the tower to sit; a rubber seal will keep gasses from escaping between the cover and the tower; the tower will have a 3 to 4 inch pipe running all the way through the tower to the top, there will be separate pipes on each side tower, this will allow the exhaust to flow freely; The exhaust is built into the tower so the appearance will not change except for the exhaust tips at the top of the tower; the tower would be double walled to keep the tower from getting too hot; at the top of the tower an exhaust tip will protrude from each side of the tower so the exhaust can escape. This will keep the exhaust up high so people cannot smell it
