Hi all,
Thought I'd pose a question*to the forum.* I have a 2002 Cummins 6BT5.9M engine in my boat.* Since I've acquired it, she's had a slight exhaust water leak at the point the 6" diameter exhaust hose joins the inlet to the fiberglass*water lift muffler.* This results in a small amount of salt water leakage (perhaps an ounce or two in a day) onto the platform on which my genset is mounted.* Last year, I had to remove the genset housing, grind off the resultant corrosion and repaint it.
The muffler inlet is slightly out-of-round, and this was accentuated by the previous owner who apparently decided the best approach to fix the problem was to simply crank down on the exhaust hose clamp, which crushed the fiberglass inlet slightly.
I've*faired*the inlet,*using West System resin and filler*and then sanding using a hose clamp as a guide to approximate the required radius.**It's better,*but there's still a slight gap.* We're talking perhaps a millimeter, and that's on the top.
Does anyone know of a flexible, moldable, removable filling compound or tape*I could use for this application (hot salt exhaust water and exhaust gas)?* Something I could affix to the muffler and then slide the hose on and tighten?
Any other ideas?
