2019 SA bags not filling

[svienb]

Beautiful day here in Texas so decided to take the boat for a run after some low 30s temps.
My boat has been down on the lift to protect from cold plus I have an engine compartment warmer.
None of my 3 bags are filling. The pumps are running but no water is flowing into the pipes, I'm guessing a block, any ideas how to fix?

Probably need to be primed. Try putting the boat in a fast idle forward, drain for a second then flip to fill. Maybe that works.

The info that @KnoxMojo listed worked for me, switch to Empty, then back to Fill when running some RPMs.

You did not say anything about turning off the ball values, assume you did not touch those.

When was the last time the boat has the impellers changed? It would not account for all 3 not working, but worth a change when you start if having any slow fill issues.

I got 308 hours out of my impellors on my 2018 SL. I started at the end of the season noticing slower fill and drain times and even the front bag not completely draining so I had the dealer replace them all. 3 of the 6 impellors were completed shot when they got in there. Not sure how many hours are on your 2019 SA but might be time to take at look into replacing them.
