dougies, you too have a problem understanding grade school English like
jeffies?

who the hell was the stupid cluck who said a wet exhaust needs an
antisiphon
valve?

Yeah, but Jax is *much* smarter than them. I bet none of the ABYC

oxxy, it is forbidden to have the water injection point below the waterline,
except the rare case when it must be. But that rare case was not the boat
under discussion.

scribbled thusly:

You can backpedal and nitpick that the water injection line is not part of
the
direct path of the exhaust gases, but its pretty clear that everyone
considers
it part of the exhaust system.



You're learning Jeff.
This is where Jocks will claim victory.
He'll be wrong as usual calling it the raw water system or some such
other but hey. that's Jocks.

oxxy, go look at a wet exhaust system and see if you can begin to understand
how it works.

kriste almighty, jeffies, the very first sentence clearly states "raw water
cooling". That ain't exhaust, dude.


Bwaaahahahahahahahahhaaa!
See!

Jocks, you're getting waaaay to easy.

Maybe you could switch back to superchargers or railways, sliding
valve engines...

phillie, it seems you are more than happy to proclaim to one and all that you
can NOT see where the water injection point is on a wet exhaust and you have no
intention of ever doing so, but you are more than happy to tell the world you
are an expert.

way to go, dum-dum.

This is total nonsense. It is quite common, even likely, that the injection
point will be at or near the waterline. Even if its nominally above, one must
add the result of heeling, and possible overloading.

The distance between the injection (with the elbow that raises the injection up)
on the new Yanmar YM series is 16 inches above the prop shaft. While this may
work out on a newer small, fin keel boat, this will very likely be well below
the waterline on a more tradition full keel design where the engine sits deeper.
And, if you subtract some for heeling and overloading, its actually hard to
imagine a setup (other than very small boat) where the injection point isn't
potentially at the waterline.

BTW, my boat, and my previous boat, has a siphon break. I was on a 43 foot
cruising boat today with a Perkins 4-108 where we determined the injection point
was just about at the waterline.

Once again, jax proves he knows about as much about boats as the Tidy Bowl Man.

No, you're wrong as usual. It is a definately forbidden to have the injection
point near the waterline with the appropriate protection, such as a siphon
break. I even posted the ABYC guideline.

Given the geometry of the most commonly used engine (and most others), and
taking into account heel angle and an extra margin for overloading, there's less
than a foot between the injection and prop shaft. Since one wants to minimize
the down angle (15 degrees is the max, but under 8 degrees is better), you'd
have to put the engine in the bow to ensure the injection point is always above
the waterline.

Here's a diagram of the boat in question, a Pearson 30. Its pretty clear to see
that even with an extreme angle, the engine is completely below the waterline.
A siphon break is obviously required.
