Change cool fuel filters now or in water?

Part of my maintenance plan this year is to change my fuel filters. I have the gen 3 cool fuel modules. I did not fog or do the winterizing cocktail on my engines. It's been 3 seasons since they were changed. 

I was going to change the filters once I got the boat in the dock in the water, but now thinking I should just do them on the hard this weekend so its done. Boat goes in, in 2 weeks. Any reason that its better to do it now, or wait until the boat is floating?

    Well, if you do them now, you won't be risking any issues or contamination when you fire up the first time to get her in the slip. And if you do spill any fuel, better to clean it up on the hard, than in the water.

    And if something breaks, you'll have two weeks to get parts.

    No reason to wait, if you can do it now, more time for boating! :)

    I change mine in the water after I have made a few runs so I burn off as much old fuel as possible.

    Thanks gang, wasn't sure if I needed to worry about air gaps or anything. Ordered two filter kits and plan to change them on the hard this weekend so its done. A mechanic did them for me in spring 16' so this will be the first time I've had them open. Found this pretty good how to on the SR site.

    one more question -  do you re fill the bowl with fresh fuel, or put it back together empty and let the fuel pump re fill?

    it will pump it back in there.  No need to add any fuel.

    I close the ball from the tank and run the motors for a couple before I open them up. Change filters close them up open the ball valve and turn the key wait and fire up. 10mm socket with a swivle for the back bolt under the alternator. I think I'm  going to change my after my shakedown cruise(54 miles).

    Filter change went well. A little dirty but could be a lot worse after 3 seasons. Pulling the plug on the fuel module and cranking the engines for 5 seconds released the pressure nicely. Did have a little water in each separator but that’s the idea.
