Beneteau Antares 710 wet exhaust hose

[HarryMacI]

Hi,

Replaced old exhaust elbow on my Yanmar 4LH-HTE engine with a new stainless steel unit as old one was badly corroded. I'm trying to find wet exhaust hose with an internal diameter of 93mm to suit new unit. I did try a piece with a 102mm ID, but it would not pull in tight with clamps due the spiral wire embedded in the rubber.

Directions to a web address or supplier much appreciated..

looks like its a really odd size - would a 90mm (if softened in boiling water) fit on? if not can you get a S/S adaptor make to join the 102 to your 93

What size is the stub for the hose to fit on the other end of the hose?

Is this hose to connect the exhaust elbow to the water-trap? How long is it and is it a straight run? What was the bore of the old hose? A picture of your layout would be helpful.

Hi,

The pipe is about 500mm long to water trap from elbow. I've attached a diagram of engine showing elbow, slight downward radius to water trap. Can I use a silicone hose that can be softened in hot water to go over the end? Just need to withstand high temperature and be non collapsible/reinforced.

Thanks to all above for info..

I‘d have thought a new piece of 90mm would fit ok, your old hose looks pretty inflexible and knackered.

 

[HarryMacI]

Yes, 90 mm ID, with a bit of fairy liquid to get it on!

Similar arrangement on my boat where that piece of hose is not spiral wire reinforced, just fabric reinforced just like a coolant hose. So if you get a piece of fabric reinforced silicone hose you should be able to make it fit but with silicone, as it is very soft, do not over tighten the hose clips.

Hi,
Looking at this product from Vetus

Talks of a ‘supple type of rubber’

‘SLANG90 90mm ID’

Vetus Exhaust Hose. SLANG - French Marine Motors Ltd

..silicone would be the way to go, easier to work with, than the heavily ribbed rubber above...just looking around here see if I can find some.

Thanks for your input Plum

Would the silicone hose have the Lloyds aprpoved wording on the side?

 

[scottie]

Removing the spiral insert often allows fitting securely

You used to get your hose made to measure with soft cuffs (no spiral) ends to solve this problem

 

[HarryMacI]

Yes, I see a lot of wet exhaust hose especially the heavy rubber with metal spiral embedded has 'Lloyds approved' imprinted on side. Guessing that if there was a fire on board that started around the exhaust the insurance agent might what to see this - if available!

Need to do homework on silicone as regards, temperature rating and reinforcement..

Scottie have you a link to supplier? ..probably less than half a meter with T bolt clamps

Thanks folks for your input.

Plenty for sale on ebay, for example, Air 1m Straight Silicone Hose Length - Pipe Tube Air Water Coolant Universal | eBay

Or Straight Reinforced Silicone Hose Coolant Water Boost Inlet Pipes - 500mm piece | eBay

The temperature resistance of silicone hose (180 C) is far higher than the epdm black rubber stuff (100 C)

Search JML Henderson, he was top man for getting hoses, any hoses made to your spec.

 

[scottie]

My links would be out of date

But portmere rubber would be a likely contender

Thanks folks, I settle for one of eBay jobs..

Will do! currently cleaning the turbo which I have removed as it was totally clogged. A few photos attached; the turbo was cleaned with a dremel tool being careful not to touch the blades. The whole thing was totally encrusted in rust and carbon. Freed up now and no play in turbine shaft so hopefully should see a great improvement in power. Only have the boat a year so probably wasn't even working when boat I purchased the boat. You live and learn! Never really got above 2000rpm and about 8knots, there was me thinking I needed trim tabs! That would have been a costly mistake. The engine max rpm is 3300
