the P30, it is clear the engine is completely below the
waterline,

no it is not.

and this is a typical situation.

plainly, you have not actually looked at a P30 engine installation.

plainly, you do not understand the issues involved *IF* one is stupid enough to
put the complete water injection system below the waterline. NOT DONE,
jeffies, and if you can not see why just shut up so you don't look so stupid.

NOT DONE.

btw, jeffies, have you ever even seen -- let alone read -- the instructions for
installation of a water injection system? You have? What word didn't you
understand?

no, jeffies, stop once and for all telling us you have an associates degree in
liberal arts physics from some technical college. If you did, no way in hell
would you post what you post. This is easy stuff, jeffies. easy stuff.
