engine hoses

[Birdseye]

how old are your engine hoses and how long do you keep them? mine are 1995 vintage.

where can I buy new at a sensible non boaty price?

Most hoses will be standard automotive heater type. Do the same job of carrying hot water from one bit to another. So motor factor through straight bits but dedicated shaped back Volvo or Keyparts.

I'm replumbing the engine bay at the moment. Combination of eBay and ASAP.

I had a near miss with an old (35yrs old) seacock to engine hose. It was the very flexible heavily convoluted rubber type and split apart where it left the sea cock. When this had happened I don't know, because as soon as I opened the seacock out gushed the water. Thank goodness I remembered to close it last time I used the engine.

I can't find a stockist of this type of very flexible hose - anyone know of one?

No need for that old fashioned convoluted hose, just heavy duty water hoe. The Vetus cataloged has Page showing different hoses and their applications but actual products are widely available usually at lower prices. Without looking expect ASAP will also have appropriate hose.

this type of hose is outlawed in the netherlands due to this happening regularly. Had to change ours on a survey a couple of years ago

The approved eu type has a blue band along it, and a wire spiral up it. It is no where near as flexible nor does it accommodate different diameters as well.

I think, for engine hoses, silicone should be durable and look quite nice and not too expensive if off the shelf sections will fit your engine ...........

For example

Perhaps indicative is/was the requirement (in Oz) for light aircraft that all hoses are removed and inspected or replaced every 6 years. Teflon types seem to be exempted. However hoses in engine bay of turbocharged engines the period is 3 years.
Now hose are more critical in aircraft but yes for good reliability you can not just believe a rubber hose will last for ever. Likewise in a car. good luck olewill

I have fitted some silicone hoses to two cars in the past year. They are a devil to get a good watertight seal with. They always seem to seep a bit. Even using a socket and wrench on the screw heads.
Rubber hoses are much easier to seal.

Cheers, that makes me feel a lot better about not having paid the premium to get pretty silicone over basic black rubber

Suction hose(internally supported) should be the only choice for the suction side of pumps,such as raw water pump,etc. Plain auto heater hose,etc can collapse,from suction.
Often the cause for engine overheating,as it collapses more,the higher the RPM's.
Any hose connected to a "below the waterline" hull fitting should be "substantial" material,preferably rated for that purpose.
A cheap hose in the above situations,can be very expensive.Double clamping them also recommended.
Corrugated "cows windpipe" ,as sold for bilge pumps,etc,& used at above the waterline hull fittings should be checked fairly often.It is thin & prone to chafing as it "jumps" around as pump cycles on/off.A leak here can fill your boat.Vetus is a good source,or good reference.
Just things I've learned over many working yrs-sometimes the hard way.

Silicone Hoses

I have never had any problems with silicone hoses. They are all I use now. You can also get them reinforced with wire or polyester if you are concerned about them flattening from suction.

Have a look at the link below for all the different types available. I use these people for my hoses, I find them very good. I have no connection to them.

Gradually replacing my black rubber hoses with blue silicone to match the blue paint on the engine

Never had a problem with sealing.
