Flushing eTec 115HO

I have a new 115HO and am a little confused on flushing after running in saltwater.  Ear muffs and running seems to work, but when I use the hose connection it seems very little water passes through.  I am used to other brands with the pee stream plus water gushing from thru hub, back out intakes, etc.  Also, I want to use Salt Away dispenser,,, best approach?

Re: Flushing eTec 115HO

Flushing your motor using the garden hose fitting backwashes fresh water through the fuel cooler, EMM coolant passage, the engine block, and waterpump. Because the water is running through a 3/8" diameter pipe, then through 5/16" hoses, there is not a lot of water flow. There is enough to run the motor at idle only or you can just let the water run for about 10 minutes. Hook up your Salt-Away adapter to the hose then to the motor if you wish. Support everything if the adapter is used so as not to put a strain on the engine grommet.

My dealer advises that the best flush is muffs & the engine running for about 10 min. I concur.
