Y-pipe failure

[pdanielsson]

Has anyone seen the flapper valve pins making a tear in the Y-pipe?<br />I had a one inch tear in my Y-pipe and the flapper valves eventually fell of and ended up farther down in the exhaust pipe.<br />My boat is a Fourwinns Horizon 18 with a 5.0 V8 and a OMC Cobra (Volvo) Outdrive.<br />The engine has never over heated and the rubber hoses attached to the Y-pipe were intact.<br />Should I just run the boat without flapper valves?<br /><br />Pd

Volvo had a service bullentin out in 95 to remove flapper valves, due to several problems with them. However, I do feel safer with working valves.<br /><br />Pd
