On the raw water side, the technique you describe will work fine, and
4 to 5 gallons of the pink stuff will get the job done. It doesn't
take long to drain a 5 gallon bucket so this becomes a two man job
unless you have an on/off switch in the engine room.

yeah that's what i needed to know...the wife will be at the kill
switch...and will run the engine at 800 rpm...just above stall
