Outdrive exhaust "sock"?

The exhaust sock (for lack of a better description) on my outdrive Ribtec has a slight tear in it that will only get larger, so would like to replace it.

Any ideas what it's made of, or who makes them?! Seems to be a much thicker material than hypalon and presumably designed to cope with heat, formed into a 10cm diameter tube that's clamped onto a transom fitting.

Do you mean the blue thingy? That would be an elephant trunk for draining water out off the deck of the boat. It should be tied up when not needed.

Yep, that (large) blue thingy - but it's the exhaust sock on this boat!

Elephant trunks are smaller diameter port/starboard.

Isn't that a Bravo 3 outdrive? In which case it should be thru hub exhaust. Does it have a valve for changing where the exhaust goes? Is the blue tube run after a muffler? Do you have an inside photo?

I have seen exhaust pipes come out the back on high performance boats but typically it is two mufflers and two outlet tips with nothing on them except the flappers. Some can be switched from cool mode to uncool mode. Loud to quiet mode. (I prefer quiet myself.)

If it is an exhaust, why not just put an exhaust flapper on?

They use to use flat water pump hose, four inch I think, they never run them through the hub in the early days, from memory it was something to do with turbo back pressure

Many thanks both.

Peter - yes, it's a Bravo 3, but this particular example has never had a through hub exhaust from what I can see, it just goes directly from the exhaust mixing elbow out the transom, with this flexible pipe connecting to the transom flange instead of a flap gate. I guess I could replace it with a flap gate, I was just looking at replacing like with like as I assume that's how it's been for the last 10 years (I've only owned for 2 years).

Biff - perfect, have found some 4" water pump pipe and that looks identical. Given the minimal cost I shall order a metre of that and give it a go (appropriately cut down obviously)!

Careful on the water pipe as some of it is really heavy duty and won't collapse as your current one will. I have some in my garage...

Thanks Peter - I've ordered some light/medium duty stuff that appears to be the same as what's currently on there, but I will certainly check it before fitting.

assuming it's the blue thing dangling in the pic, it looks like layflat hose, I thought it was the elephant trunk bailer.
