What is that od of this fan ? 64mm ? cause i had a few say it’s close to 70mm and won’t fit in 64mm jets .

64 mm is the diameter of the fan blades not the od of the duct. I don't exact od of the housing mine installed and is surrounded by foam but it usually 1/2 -3/4 bigger than the fan od.

Will this help and work with the 64mm 3s freewing f/a-18 edf jet "royal maces"? is it worth upgrading?

You'll need to compare the KV and the thrust ratings. I used it on a Neptune flying wing replacing a noisy 5 blade. Its very quiet compared but i believe i lost just a bit of both thrust and speed. I'm not a full throttle flier so top end isn't an issue and I appreciate the tone of this EDF.

My motor is not turning it’s just beeping what does that mean?

Try another esc make sure do not use more than a 4 cell battery. Either that or if you use a opto use can install a ubec to power the servos and receiver. Total cost about 20 to 35 for upgrade. Motor ok but esc cheap.

Can it go underwater?

I think it may be not， unless you make a sealing device to seal it
