I have recently purchased a Carver 444 2003 model, we sailed the motor yacht from Victoria to New South Wales Australia( 649 nm) and have been experiencing exhaust system failures, the fibre glass exhaust tubing on the starboard engine is delaminating and leaking water and exhaust fumes.
On the sea run prior to leaving after I had the engines serviced the first exhaust section after the turbo fell off due to weakening of the end of the pipe, we replaced that section with a stainless steel section however the rest of the system is leaking fumes and water through the skin of the pipes,
they are also getting soft.
I have located a US Coast Guard recall No 070042T that refers to muffler problems, is anyone aware of anything in reference to exhaust tubing and a replacement /repair methodology.
