Seeking a little guidance from those who may have experienced similar or made repairs.
We have twin 12V71TI’s in our boat. The wet exhaust manifold come down from each turbo, tying into a cross piece that is graduated larger as it approaches an elbow, where is has a 10” straight section.
That is the exhaust manifold it then is connected with a short section of exhaust hose to the fiberglass pipe and mufflers headed out the stern. I noticed some leakage at the straight section directly after the elbow, probably mild corrosion that began at the welds.
The boat is in Mexico and sourcing materials and quality tig welder can be questionable, so I am exploring repair options.
One option is to take a small tig machine and two pieces of stainless tubing 10” diameter 10” long, cut off the straight section and weld new on….
Another option I was considering, but not sure if it is acceptable practice, would be to sand down the stainless and glass it. Fiberglass materials are readily available down there. Is this an acceptable idea? Will fiberglass bond to a roughed up stainless? I would wrap the entire circumstance for strength.
I used a piece of exhaust hose and some spare clamps as a temporary repair, so it is not leaking, but that was a temp repair only.
Any thoughts or feedback would be great! Thanks!
