Do I need a fuel water seperator on my boat?

Probably... but not necessary as kamie already mentioned. The engines have an inline filter already so that stops the dirt and the tanks can be checked for water if necessary and dumped. Not like a built-in tank where you are basically stuck unless you siphon out the tank... That is where the fuel/water separator really earns its keep. A 1993 without VRO...?.. I hope you like to pre-mix

Just happened to my neighbor. Fortunately for him it was in his tractor and not the boat, so he pulled gas from the boat and got the tractors running.

Aside from the water separating ability, just having more filtration is never a bad thing, especially depending on what you have under the cowl for an in-line filter. Most spin on filters can filter from 10-28 microns, depending on the type. Dave - 1983 Outrage 22

While you're in the store buying your new filter get that handy measuring container for the oil mixture so you won,t mess up. Enjoy the Whaler as much as you can before,you know, WINTER.

On mine, once you take off the air silencer and the carbs, you can *almost* reach the filter. OK, I exaggerate, but not by much - if yours is as hard as mine, take off the inline filter and put on an external one. Tim

You can buy good clean gas and end up with significant moisture in the tank just from the condensation that forms on the inside walls when we experience the higher humidity levels in the summer months. One way to help limit the problem is to keep the fuel level as high as possible but that isn't always practical. I run a separator/filter on all my boats. I know of no good reason not to. With the higher ethanol content of most of today's gasoline, I'd say its a better idea than ever now.
