We have a 61MY with 12v71s and just noticed rust under the exhaust elbow before exhaust heads through the wall to mufflers. This is the last bend on the riser to send exhaust out of engine room. Appears to be like 12-14" diameter stainless maybe 30 degree elbow with hoses connecting to it triple clamped.

I have googled and cannot find a supplier?

Any help much appreciated!

Tks!
