Have a Honda 9.9 2001 model,has been terrific engine but now will not idle consistently,I am told that the exhaust has corroded through from the inside and the back pressure is required to perform properly,is this worth repairing, it has a ton of hours on it and still runs, but will not hold a trolling speed that is steady, can you remove the system with the removal of the cylinder head???
