yes, i have an actual boating question

I replaced all the 3" exhaust line on the engine (10', a bargain at
$2/ft!).

NOW i need to replace all the cooling lines leading from the seacock
to the engine, and the engine heater hose. the engine has a heat
exchanger and is cooled with an anti-freeze/water mixture.

so why type of hose should I use? is there a marine grade or can i use
the regular heater hose used in cars? rubber is pretty impervious to
salt water....

hope it's cheaper than the damn exhaust line!

thanks all

Somebody will probably differ with me, but I don't see any reason why
you can't use automotive. Hoses last on cars for 200+ thousand miles
in some of the worst under-the-hood conditions. My two GM powered
boats are fresh water cooled and I use automotive.

Even on an enclosed system like yours automotive should do fine as far
as I can tell.


Yes, automotive is fine in a marine application such as this. It's actually
better, since it costs 1/2 as much.
