[OMC-Boats] Tell Tale stream

I have a question for the group-
How dependable is the hose bib method when doing engine test/tune type things
with boat on trailer. I read in the SELOC manual to not exceed 1200 RPM when
using hose. I'm concerned it's bypassing the impeller and forcing water into the
engine vs. being pulled up by impeller. I get the stream when i use the hose,
but had the nagging question in my mind. Am I all wet, pardon the pun, and just
not smart enough to know how the lower unit works?
