Chris, If you can without to much trouble, put them inside the fuse. If not, the hoods will work too. Seal any opening around the servo with silicone. You'll be suprized how the water can find it's way into place's you don't want it. A small o-ring under the horn around the output shaft of the servos is also a way to help stop water penatrateing the servo.

Good Luck.......
