I tried silicone hoses water but found that i damaged the outer sheathing while wrestling them into place.  Probably my fault.     Reverted to the rotax spec.

As for changing rubber every 5 years i see it as an opportunity to have a really good look around in those inaccessible areas.

I used parker 836 pushlok for oil on buds recommendation and it has worked well.   I protect all hose with thermotec velcro sleeve.

Hi Jonathan,

Europa Aviation sell silicone hoses for oil and coolant and they are excellent quality. The oil return line is moulded to the correct shape for the return to the oil tank. In my opinion, for that hose it is certainly worth using silicone as it is directly above the exhaust system. Sheath it with Thermotec sleeving or similar anyway to help protect it. The biggest risk to silicone hoses is cutting them with incorrect hose clamps.
