Anyone have first hand experience with life expectancy of dry joint exhaust. The reason I ask is I just bought my first boat and it spent 7 years in salt water. I pulled the riser elbows (manifolds and spacer blocks coolant cooled) to inspect and see some corrosion but nothing major but you can't see to much inside.
What I don't get is this system is not new but has been out since 2002 and still its hard to find real world reviews ! I know there are so many variables with each boat/boater being different but when I google and google more about failures or when to replace there is basically nothing. Maybe this is good sign for the new dry joint system. There are more guys out there like me asking for how long people get out of them instead of stories good or bad. I know the old wet joint was 5-7 years max but if mercury developed this new better system (thats costs a lot more for the parts) why are we still doing 5 years replacement
It seems most failures were at the elbow to gasket area of the old system and that is impossible with the new dry joint. But how often do they corrode right through the metal inside the elbow ? And do I want to be the ginnie pig running the new system longer !
Thanks
Dave
