I have a suzuki DT85 and it does have a flush port but I've never used it.
I got a large plastic water cistern from the builders merchants. Full, the cavitation plate is just covered and the exhaust is quiet. I keep the hose running slowly to keep it topped up as lots of water squirts out of the tell tale all over the drive - or me
. My boat's usually on a mooring, so only gets flushed three or four times a season, so when I do flush it I run it in the tank for 15 mins or more, which I hope will help dissolve any salt build up. You have to watch that the water doesn't get too hot though. Also, never put the engine in gear - it'll empty the tank in half a second.
