Jax;

I'm really truly starting to wonder if YOU understand what is happening
in a wet exhaust? Jax,do you know what the raw cooling water is doing.
The engine coolant is Ethylene Glycol. Tell us, Oh Wise One, what
happens to the raw cooling water. Is it used for washing dishes?

Ole Thom
P/S I still waiting for you to tell me what the Tel-tails, that were
set-up to trim sails for Bernoulli Air flow, are doing with the
Newtonian System. Are they wrong? Shouldn't we set sail trim by them?
The ones on the ACTION SIDE of the sail seem to respond just like they
did for Bernoulli. Where and how can I observe the effect of the
REACTION of the Newtonian Force (F)?
How do I trim sails using Newton Laws of Motion?

Why do
the Jets deploy Slots and Flaps at low speed?

it makes the wings larger.

old man, it is plain that you are no longer capable of coherent discussion.

naive, the only time the "last two words" have any import is when you
(hereafter referred to as yo-yo) crank a non-starting engine over for an
extended period of time (during which yo-yo has left the cooling water intake
open) until the entire exhaust system downstream of the waterlift muffler has
been filled with water and yo-yo has loaded the back of yo-yo's boat down to
the point the exhaust outlet is under water and the exhaust outlet from the
muffler did raise sufficiently (yo-yo installed the outlet hose wrong) so that
the muffler inlet hose also fills with water yet the engine manifold outlet is
high enough yet still below the waterline that the *entire* downstream exhaust
system has been filled with water ...

.... and then at that point yo-yo stops cranking the engine and settles back to
letter the water flow.

far more likely in the above situation (in which yo-yo has improperly installed
the exhaust system) is that the water lift mufler fills up first and water
drains back into an open exhaust valve.

which, of course, would not have been prevented by any anti-siphon valve
because no siphoning occured.

you see, a yo-yo is a yo-yo.

Ok here's a direct quite. Read it slowly. Take your time.

"Problems occur because on almost all sailboats, and on many powerboats,
the engine is installed below the waterline. Even if it's not below the
waterline when the boat is at rest, the engine may well end up there
when the boat heels, or when it is heavily loaded. This latter case can
be particularly dangerous: because the boat's designer or engine
installer may not have adequately planned for it. If the engine is or
any time below the waterline, any cooling circuit that allows raw water
into the exhaust has the potential to set up a siphon action. Water may
siphon in from the water injection side; or, if the exhaust outlet is
below the waterline, from the exhaust outlet side."

See the last two words???

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?

you can't siphon water uphill using the weight of exhaust gas going

downhill.

Umm... no.

If you crank a non-starting engine for an extended period of time, the
"entire exhaust system downstream of the waterlift muffler has *NOT*
been filled with water" because the engine valves and cylincers have
been pumping air the whole time.

I think the whole point is that without a siphon break, it is "improperly
installed." If the original poster (with a Pearson 30) does not have siphon
break he is at risk. Since he stated quite explicitly that he was powering with
a following sea, turned the engine off, and then found water in the cylinder,
and we know that his engine is below the waterline, the lack of a siphon break
is a reasonable suspicion.

Jaxie, you're totally busted here - you clearly have no idea what you're
babbling about.

jeffies, go stand in a corner and be quiet for a while. adults are having a
conversation. when you talk some newbie might mistake you for an adult and
your religion won't allow such deceit.

Ah, jaxxie is now admitting that he made a complete ass of himself, yet again.
This is his childish way of trying to save face.

But it is fun to watch isn't it? I love the standing in the corner bit!
