Ordered 4-Stroke kicker motor, should arrive this week....The Fuel/ Water separation filter has two 'IN' and two 'OUT' ports. One of each is obviously being used now, can I run the kicker off of the other 'OUT' port ? Rob

Yes.

I did this and it worked well with one exception- I had removed the pump bulb from the kicker and the main engine would suck air thru the kicker. This happened because there is a valve in the bulb that prevents fuel from flowing backwards in the line.
I resolved the problem with a fuel tank switch after the water seperator. But leaving the pump bulb in the kicker fuel line probably would have fixed things too.

Installations with one-filter/two-oulets are fairly common. Use two primer bulbs. Locate the primer bulbs within two feet of engine.
For the ultimate in redundancy, have a separate small tank to run the kicker. If you get a load of bad fuel in the main tank you can come home on the kicker and the auxullary tank.

I'm with JimH.
One of the failures that would leave you dependent on your kicker to get home is a fuel supply failure.
Even a 2 or 3 gallon auxilary supply can get you a long way with your li'l 4 stroke.

Rob,
When you install your kicker and run it off the same fuel tank as your main engine, you need to make sure that you do not create a situation where one engine can suck air through fuel line feeding the other motor. What happens is that air may seep through the fuel connector for the kicker and sucked into the main engine. You can burn a motor up by doing this. The best way to prevent this is to put an on/off valve on each of the out ports on the fuel/water seperator and then attach your fuel lines to the valves. When you are running the main engine, close the valve to the kicker. When you run the kicker, close the valve to the main engine. This is a much better situation then relying on the bulb or fuel connector to prevent the introduction of air into the system.
As others have said, you should also have a separate fuel tank for your kicker so that if you have a fuel supply problem, you can run your kicker off of the backup tank.
