Sticking hoses?

I have many parts of my boat in bits this winter and cleaning, painting and updating where I can but I like to be able to get things to bits without damaging or wrestling for hours if the need arises so everything is put back together with grease and a bit of care but one thing I never get on well with is hoses, mainly bilge hose and exhaust.
Anyone got any tips? I recon some silicone grease on the bilge hoses might help but can't think of anything to stop the exhaust hose welding to the elbow again
 
I really can't imagine many cases when you'd need to disassemble exhaust or bilge hoses. Most people never ever do it.

Yes - don’t deliberately make it easier for hoses to come off their fittings and sink your boat :)

I was struggling to install a hose over the end of a spigot, and after hot water failed I decided to use some silicone lubricant. The hose went over the spigot all right but wouldn't stay on, however tightly I fastened the hose clip, and I had to spend ages removing the silicone again. (On a basin waste, well above the water line fortunately.)

Large patay manual pump in a tight spot which has to come out if you need to do seals, loads of swearing involved, exhaust isn't such a problem but I was close to ruining the hose getting the elbow off to inspect it

I use silicone grease on all the hoses I have ever put on the boat or on a car going back 30 or 40 years. The hoses on on a car cooling system are operating at a much higher sustained pressure than any hoses on a boat and I have never had a hose come off when not required to, and car hoses are not double clipped. Mind you, my boat ones are not double clipped either.

Having said that, I have never used silicone hoses. Whether I would silicone grease those is a bridge yet to be crossed. :)

if you dont have a special tool, the key is to push and turn, not to pull as may be instinctive, if you push and turn you will eventually break the seal

Obvious, now you mention it!

Pushing will tend to increase the diameter and hopefully loosen the bond, pulling will reduce the diameter and tighten the hose.
 
not just me then - tried removing exhaust hose from high rise elbow a few weeks ago - lots of effort - not a jot of movement - in the end having blown through the hose and felt as much of it as I could and inspected exhaust outlet from cylinder head etc with no sign of any carbon buildup - bolted riser back on and called it a day - mind you knuckles and fingers suffered as usual - confess did not try pushing and turning - next time!!
 
Push and turn works well on coolant hoses with a bit of give in them but that reinforced bilge pump hose that goes hard as plastic is never playing ball, exhaust hose was days of penetrating spray with a small screwdriver pushed down and wiggled then a big hammer eventualy to break whatever was catching
 
Those tools look helpful. I have had good luck with an old hair dryer. Gentler heating than with hot air gun.
Also, for hoses with spiral reinforcement, twist first in the direction that unwind the spiral, not the direction that tighten it.
