I doubt that there are very many portable pumps with 6' piping.

I doubt that too; the ones with which I'm familiar tended to be 14" or smaller.
The larger ones with which I've dealt are not designed to be portable (they're
self-contained gasoline or diesel fire protection system pumps), but a small
crane can place one on a flatbed in jig time. They don't have to hook up to the
existing plumbing. Drop your inlet in on one side and drop your discharge line
on the lake side. Again, the pieces for this (including inlet screens) are
readily available in the fire protection world. One of the larger units can pump
water ten stories up through a 12" main.

In any case, as I said, any major port will have large portable pumps. The
largest are used for salvage operations.
