Engine exhaust leak

[Bostin]

Some advice please. While there have been some previous discussions on exhaust leaks, I had a few questions. The leak is from the flexible pipe although I can’t see a hole. If I approximate where this is can I apply a sealant? Which one?. Or, should I come to replace this flexible pipe, how do I remove it- there is a sealing at each end. And when I come to insert new one, what do I seal this with?

I think there is another pipe inside that woven covering.

Buy a replacement.  The end of the pipe screws into the fittings, (the bit with the red ring of rtv sealant).   The other end is probably similar.  Some pics of the whole exhaust might be helpful.  

 

Get em tight and use copper grease and the joints won't leak.

 

Midland swindlers sell the flexible pipe with BSP screwed end fittings. Check your size carefully

I had a leak on a 'flexible' exhaust that was a bellows pipe rather than the OP's braided hose. I effected a temporary repair using Gun Gum silencer paste, an opened up baked bean can and a couple of large jubilee clips. But it it was a bodged up short term repair (since replaced). The best thing for the OP to do is replace the whole hose, using a Midland Chandlers or similar new pipe as suggested above.

I was going to say similar,

you can make repairs,

but from experience with exhausts it’s always gonna be a ‘bodge’ to get you by,

 

best to buy and fit a nice new shiny part and forget about it for a decade and more 👍

Thanks All for advice. I’ll replace. Could only send one photo as shown in Ist post. I can see here male end of hose disappears into elbow. Now include here the other end( where the leak is)- thread  appears part of elbow?? I’ll move nut around  when next on boat to see connection better.

The hexagon nut looks like a navy union. Undoing that will  release that end and you can unscrew it from the hose leaving only one fixed end to unscrew.

Wot  x brummie said. You will need at least two pairs of biggish Stilsons (24 or 30 inch) to get the nut undone without the elbow moving.  A big blowlamp also helps.⁹

 

 

Probably similar at the other end.  Hold the elbow, turn the flexy pipe.
