Flushing Cooling system from tstats down

Hi Crew,

I bought a 2008 BF200 engine (with 350 hours on it, so obviously its chocked full of scale and crap) a couple months back and have been having overheating issues. They seem temperamental, some days there is no alarm, some days I cant rev at all without the overheat sounding.

I have had the water jackets off and scraped out along with an acid flush. This seemed to largely do the trick but the problem has come back.

Some days, I cannot rev high at all and some days it beeps when i take off, then i throttle back and go again and its fine up to max throttle.

I have read that taking the leg off, the tstats out and flushing from the top down with acid is a good option, but how do I do this?

Thanks
