It is incredible what one can learn on a usenet group. Why, just today, I
learned wet exhausts need an anti-siphon valve installed. I bet tomorrow I
learn that sails move a boat forward "because they are curved on one side".

Read it and learn:

dum-dum, *that* antisiphon valve is NOT in the exhaust.

what a dumb cluck.

Also, it refers to a *cooling* water hose -- before the exhaust -- said outlet
of which is ------ lower than the waterline ------- a forbidden practise, and
in most engine installations damned difficult to install incorrectly.

what a dumb cluck.

Where did I (or anyone) say the antisiphon valve is _in_ the exhaust?

Now tell us why you think you don't need an antisiphon valve. Vague
references to gas laws are required.

the discussion was about a wet exhaust. It was NOT about an installation done
prior in a forbidden manor. the guy had not had a problem with the boat
before, therefore the water injection point was not (through impropper
installation) below the waterline.

On 02 Jun 2004 01:23:06 GMT, something compelled
(JAXAshby), to say:

It was NOT about an installation done
prior in a forbidden manor.

Why is the manor forbidden? Is it haunted or something?

you can't siphon water uphill using the weight of exhaust gas going downhill.
dud!

OK Oz,

He is on good and solid. He hooked himself. It's a double. You play him
for awhile. When you get tired I'll work him for awhile.

Ole Thom
P/S when you get to condensing gas I'll take over. Have fun

Dud? Let me explain at a level a child should understand. You run the
engine -it gets hot. You turn it off. You raise the sails so the boat
heels and puts the exhaust under water. The engine cools and water gets
sucked in 'cos the siphon break valve no longer works...

get it?

Jax,

I hope this doesn't surprise you to much but look again at any sail
working. You will see that both sides are curved
