Looking for Flexible 1 1/4" hose

[rebel heart]

I've found some like this but they recommend "not below the waterline":

SHIELDS RUBBER Series 120 Bilgeflex Bilge Hose at West Marine

The one I have probably shouldn't be below the waterline anyway but it's how it's configured. I can't run a stiff-walled (sanitation, fuel, etc) hose.

Anything from West Marine / Port Supply I should be able to order into La Paz here via Lopez Marine.

They mean not to connect to thruhulls below the waterline. If you are connecting a bilge pump to a thruhull above the waterline, then this is OK.

However, that stuff is very thin and cheaply made. It is easy to break or get holes in it and it kinks easily. And the corrugation cuts the flow down by a lot - severely de-rating your bilge pump.

You can't use vinyl hose or the exterior-ribbed vinyl hose? This stuff is much better and can be bent into small radiuses without kinking.

I asume they mean as a pressurized hose below the waterline... (meaning one that is on a seacock feeling the sea water pressure.) as a bilge hose that exits above the water line it wolsnt be "pressurized".

It's for the head sink drain, maybe a 14" run, but it needs to basically bend out 40 degrees then bend back in to accommodate some other plumbing. The stuff I have now has a black exterior with a grey ribbing on the outside; it works great but I can't find it anywhere and am not having much luck online.

Sink is above the waterline, thruhull drain is obviously below.
