My boat is going on 8 years, it is trailered, flushed and preserved with salt away every use. What actually fails on the dry exhaust system and if I pull the risers what exactly am I looking for? I have read on some sites where others say to just run them until you see a temp rise that any leakage will be external. Researching replacements it seems there are non except for mercruiser oem dry joint parts. I got 7 years out of my old boat exhaust which was not a dry joint system untill traded for my new 289. How can you tell on the manifold of a dry system if a problem is developing?
