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.

that's what i was hoping for! for the prices they charge, it'd be
cheaper if marinas just made their stuff out of money...

yeah, i think so too. the hose is just going to see hot water, and hot
salt water...neither of which should affect rubber....i'll let you
know if i sink (again!)

I use good quality automotive water hoses. Not had any problems with
them.

The easiest way is to slit them with a razor knife and peel them off.
Less chance of breaking the barb.
I usually cut them back a couple l inches from the barb, slit them a
couple times and peel them toward the barb like a banana. Less stress
on the barb.
Two pairs of long nose pliers works well.

thanks for the advice...yeah that worked pretty well with the exhaust
lines...scotch brighted the fittings, too, to get all the old crap
off. real mess. i used to have a twin engine boat...working on a
single engine boat is a snap compared to that...

If you can find a premium grade heater hose it should be fine but a
lot of auto parts stores sell junk.

thanks for the info...thought that might be the case.
