I've wondered about this too. My compromise (no expert) is to use regular antiseize when antiseize is called for (it can lead to bolt over-tightening, I'm told) when direct seawater exposure is not an issue and the bolt and hole metals are similar. I gather some like the teflon thread sealant compounds.

I definitely would not use antiseize here that contains additional metals, and furthermore I've been told not to use any compounds between stainless shaft and bronze prop, or in the keyway, but to make sure I have adequate zinc on the shaft.
If either of these understandings are wrong, I hope to be corrected.
