Water/Fuel Separator for 03 Yamaha F90

Took the boat out for first long run of the season (live in FL) and have been running her on trailer every month or so. I had problems with stalling out after running a while. Had kids on board so took a tow back in (I was almost back at dock at end of day when she gave out). I am thinking it is a water problem with my separator but wanted to see if anyone had other ideas. My plan is to first replace the filter on the separator, then check the fuel filter in the engine see if the there is water in there. Tank had new gas in it, but I am sure some condensation occured and water got in there.

Update - the dealer is suggesting I bring it in as the carbs need to be rebuilt! Pretty stern diagnosis with little input.
During lunch hour, I took out the fuel filter and yes, the float was floating! Little water in the mix, but a slight bit of sediment as well. (what is the best solvent to rinse the filter out with?
Second, I took off the water/fuel separator and it was loaded. Will replace that tonight with a new one.
Before I headed out, I filled up (close to it) my 27.5 gallon tank - adding about 10 gallons or so. I suspect the water (if that is the main culprit versus some sediment which I know can cause problems) was from natural condensation since I didn't close the release valve on the tank since last start. Could that be enough water to force me to drain the entire tank and start new? There was plenty of fuel in both filters as opposed to lots of water. Lots of junk in the separator.

make sure your all fuel lines and the primer bulb are in good condition.

Ran strong over the weekend! No water floating in the filter.
I did hear a sort of 'spit' sound as I was just starting her up, could that be the h20 leaving the building? It doesn't do it anymore.
next, installing a new depthfinder/recorder...
dealer said I would need to rebuild carbs. I guess the warranty work is good work. It took a new water/fuel element, cleaning the fuel filter out, and a good running with new fuel.
