In response to: "If there's enough water in the fuel tank to fill the separator then you're still skrewed. The rest goes right into the engine."
I believe the water-separating fuel filter will not let any fuel thru if it is full of water and the engine will starve of fuel. It doesn't start letting fuel thru if it is full of water...

They do not stop the flow of fuel or water at that point. A separator that is "overwelmed" is the same as not having one at all.

I contacted my local Mercruiser repair place and he also told me that once the fuel filter is full, they starve the engine of fuel. He told me he just had a 24' boat in last week which would not run at all, the filter was completely full with water, replaced the fuel filter and everytime ran fine. So now I confused as to which theory is correct...

Take a hammer and sharp chisel and carefully carve off the bottom of the can.
Take a look at that and ask yourself "what magic would stall the engine after it's full of water"?
Answer - There is no magic. It's just a dumb device that is for basic protection.
Now if there were an actual water sensor that was linked to a computer/ecm or a dash mounted indicator of some sort then you would know for sure. However, even the water sensors on the expensive Durmax engines is still a piece of crap. It does NOT work all the time and it is linked to ecm and dashboard indicators. The cheapest and best way is to change if often or keep using it and buy engines.
Sorry, there is no "starve" capability in a spin on filter for 8 bucks.

Don't listen to others entirely. Put your old filter in a vise just well enough to hold it.

Thanks again everyone!! Got the boat running yesterday!!!!!! Changed the filter and surprise surprise, water droplets float in it. Put in a couple bottles of K100 in the tank, a quick shot of starting fluid and started right up. Stalled a few times but eventual ran pretty smooth. I put 15 gallons of 93 in it and ran almost all of it out yesterday. Changed plugs today, and plan on going out tomorrow afternoon. Again, thank you all for your input!!
