In the manual I got from Tiara they want you to drain the tank instead of pumping tank empty because pumping leaves more water in tank as opposed to draining.this is important in that you would have less water to dilute the concentration of antifreeze you put in.only problem with that is when you can't access drain and have to just go with pumping out water .tiara said to put 5 gals of the pink stuff in but I didn't have the temperature protection I wanted so I had to put more in to achieve that.it would also be nice to know where pickup is also so you would know if maybe you should winterize before pitching boat up for winter.i suspect pickup is forward and this led to residual water in tank necessitating extra detox to get concentration to proper level after pumping through system.bill
