Oh Gawd! I didn't realize my email still has that corny old
"Captain Nemo" identity designator on it! I'll have to check
with my better-half to see how to change it. ;-)
Don't do it! Nobody else has a Nautilas. Besides, it's too
late. We already saw it. I think it's a great handle.
One of my new projects is a 16-foot-long high-performance minisub
shaped something like the SKIPJACK.
Very cool!
I've got a jetski drivetrain I want to install; but I was reading
through the archive, and found comments about additional "air"
being necessary to eliminate a vacuum at the impeller, and this kind of
throws me a curve. (Looking at my KAWASAKI JS-500, the only vacuum
line I see near the impeller is one that draws water from the bilge via
decreased pressures induced by thrustor-flow.
Maybe it normally draws air, but has the secondary purpose of
evacuating water?
Is there any reason why a small portion of the engine exhaust couldn't
be routed to that area to serve this purpose?
What about the balance of the exhaust? Where does it go?
Anyway, I'd like to hear more about why additional air is necessary at
the thrustor water intake from anybody who really understands this
principle; because it's news to me, and I'm about to dissect a hull
and bolt a squirt-drive into it.
I'm curious too.
