Not sure where you got the idea that the 3050 is waterproof. Futaba does not list it as such. And they do not call any of their servos waterproof, they use the term water protected. The 3050 is a great servo. I use the 3152 for throttle. Still a good digital and much less expensive. About $20 less than the 3050.

I use the 9156 standard case servo for rudder. 340 in-oz of torque and a very strong gear train. It is "the" Futaba servo for giant scale planes and mine have proven solid in boats. Even a couple of 75mph+ blow overs have not hurt it.

Sorry Silent, I meant the S5050. It is indeed waterproof and has rubber gaskets between the case halves and splined output shaft.
I had it sit underwater for almost an hour when my cat flipped and I couldnt get to it and it remained dry as a bone inside. Great servo.
water proof or water protected...is the wording really that different? If its "protected from water" That says to me that water cannot get inside. So Iguess the word waterproof can work as well. You may not see it that way but its all good. it does not let water in, so either play on the word will do
Sorry for the confusion.
