Unless the blower is sumbergable (none that I have ever seen are) you would
want to take care to mount the blower higher than any
----------------------------- expected ----------------------------------
accumulation
of bilge water. Even unexpected amounts!

expected??? unexpected? who the hell is worried about butane in the bilge
when expected (WTF is that???) water or unexpected water is in the bilge?

if you intend to have water in you bilge, there is still NO need to mount the
blower "up high". just mount it above "expected" or likely "unexpected" high
water level mark.

duh.
