    not very. pretty stout stuff. the ribbed stuff seems to bend a little easier. but neither is easy...

    you can try using boiling water. pour it on the hoses in a bucket or tub to soften up the hoses. If they are off just a little towards the ends spray them ( the ends on both sides) liberally with WD-40.

    Been through BBO to BBf and then changed log style on the BBF with same hole in transom. They are slightly bent but double clamped both sides. They go down and out...I did shave the part of the hose just a tad to fit more snug on the snail.

    Default silicone hose

    I used 4" silicone high temp hose on my TT exhaust. Super soft and flexible, comes in several colors, 45s, 90s and is reasonably priced. I ordered mine from siliconeintakes.com.

    Have you been using that hose long enough for it to prove itself? I looked in the exhaust section of that site and didn't see any rubber hose rated for exhaust.

    I ran it 2 years with no issues. I was concerned at first but the pressure and temp rating exceeded the rubber that had been being used.

    Silicone should take the heat as long as there IS water present in the hose. It works well for short relatively straight apps. Longer stuff with any bend it will collapse as it is so flexible has no body to it.

    "Soft wall" is great but has no structure and wont effectivley make any bend or turn, "hard wall" is heavier and worse to form than soft , ,corrogated (ribbed) is good for any type twist and turn but doesnt clamp well consider using aircraft type band clamps when using corrogated Tom
