G’day all.

Looking to replace the set of cooling hoses on Cast Away’s twin Mercruiser 170’s.

The hose from the intake manifold to the water pump has ruptured.
Crowley Marine identify the part as 32-76326 and No Longer Available.
NLA seems very correct as I’m having a devil’s own time in trying to locate any source to a replacement item.

Is anyone out there able to point me in the right direction for this hose, or a complete set of new hoses?

Maybe a Sierra equivalent, or some other equivalent?

Cheers all, and a Happy New Year for 2019.

Look up the Gates molded hose guide and compare the hoses you have....then locate the hose under the gates number

Chris, I came across that little gem 30 years ago..... makes it perfect for hot rodding as all my hoses looked "factory"

many times you may have to buy two $8 hoses to figure out which one is the correct one.

it has been invaluable making gensets, custom pump packages, etc. when I worked for Cummins we had access to the gates engineering library and they would provide the X, Y, Z bend info so we could accurately model the hoses.
