Small outboard fuel water separator?

[gbillman]

Is there such a thing as a fuel water separator that splices into the line from fuel tank to motor for a small outboard (i.e. Yamaha 15hp 2 stroke)? I've got an in-line filter now, but was wondering if I'd be better off with a water separator (given the propensity of small outboard carbs to corrode internally with even small amounts of water). Thanks.
