While cruising to St. Petersburg last week I found saltwater emerging from under the starboard side water tank. A puddle of water under the muffler and products of combustion in the water made me suspicious of the muffler.
The hardest part of removing the muffler is getting the two 3" exhaust hoses disconnected.
The muffler's small leak.
Leak close up.
With the muffler out it was obvious the leak was from its starboard side. The staining means it has been leaking for awhile. The muffler was made in two parts: top and bottom. The two parts were then mated with a band of fiberglass. The leak was found at the bottom of the mating band.
The 11' x 3/4" (id) raw water hose from the engine room to the PSS and intermediate bearing was removed. It needs to be replaced.
The rudder packing gland was tightened. It'll need to be checked while we're underway, only then, with the stern squatting a bit, does it leak.
