Also about fill times. I’m not familiar with the 2011 but if it has 3/4” hoses and if you want faster fill times you will want to go up to 1” lines and you will have to increase thru hull size also to 1”. The 1100 with reversible pump fills and drains in around 5-6 mins with 1”.
Head over to Centurion owner Facebook group it has a lot of info on it
