How long do you guys usually run the water for when flushing the cooling system with fresh water ?

Could not find duration period listed in the manual ?!?!?

Thank you
 
@JetBoatPilot did a nice video:


The my manual says 10-15 minutes each side which is a waste of gas.

My saltwater procedure 3 mins each side with salt-away left in (rather than a clean water rinse at the end of the flush). I do this after every use in saltwater.
 
About 10 minutes with fresh water. Then do it again for about 3 minutes WITH the salt away. This way, the fresh water does not wash away the salt away residue, which defeats the purpose of the salt away.
 
Holy heck that's a long time.... 3 ish minutes is plenty....
 
I flush with clean water 10 minutes than switch over to salt away for 30 seconds
