I assume you're talking about a connector for a garden hose coming off the head somewhere? If so, then no you do not need muffs, and you do not need to run the motor (most mfr's say specifically *not* to run the motor when flushing this way, though Suzuki's website had an instructional video showing them running, even with the text saying not to - go figure.) Connect up the hose, and let the water flow through for 5 to 10 minutes (or however long your patience allows.)
If you run the hose to a set of muffs, you *may* need to block off any water intake inlets that are not covered by the muffs (I used duct tape.) Some motors only have a pair of intakes on the side of the leg (which means you're good to go); my Honda 40 had those plus an intake on the bottom of the anti-ventilation plate (which needed to be blocked.)
Hope this helps;
