IF an antenna is rated at 50 watts, and you have a radio that can make 65 watts, is it safe to transmit that 65 watts?

There is always a risk in operating things beyond their design limits . Even the stated design limit may actually mean use at the limit occasionally. Higher than limit watts means heat that might destroy insulation or other components.

Generally, one should go in the other direction. If you transmit 65 watts you should use an antenna rated for at least 100 watts. If your antenna is rated for 50 watts then you should transmit no more than about 25 watts. Most mfgs will rate their devices at the maximum it will handle under ideal conditions. For an antenna that means with a 1:1 SWR and for a limited transmit time.
