Terminology for hose

[robertager1962]

Hi all
I need to order some below waterline pipe to replace engine cooling water inlet (1" ID) and cockpit drain (1½" ID)
What should I be asking for?
If I were in the UK I would just ask the above but I am in Spain and my Spanish is not technical.
Checking on SVB and ASAP I can't see what I would expect to see ie spiral reinforced hose.
Can anyone tell me/send me link of what I should asking for please?

Not spiral reinforced which are normally for high-pressure applications. But assuming your engine cooling water hose runs close to the engine, it must be heat resistant.

Inlet may need to be spiral (or otherwise) reinforced to resist suction?

Thanks Andrew. No not near the engine, I have installed a strainer in the engine bay, which the pipe is feeding. However my slight concern is my engine is a 36hp and should the inlet become slightly blocked, I don't want it to collapse.

The water inlet hose should meet two requirements: fire resistant so that it does not burn through in an engine fire, resulting in sinking, which is a rather drastic way to put a fire out, and not collapsing due to suction if the water intake is blocked. The relevant standards are ISO 13363 2B and RINA DIP 123816/CS , either or both of which should be stamped on the hose. Once, having struggled to remove an existing inlet hose and replace it with the above specification as required by a surveyor, I found these numbers on the underside of the existing hose that I had just mangled!

Thanks for this and I feel your pain
