I finally got 1.7.0.2 to sync after many retries and experiments.

I think it may be due to one of the default nodes still being stuck at 83111   (addnode=107.170.217.4 ... this was yesterday)
It appeared that  my cleanwatercoin client was using this node, since it also kept getting stuck at 83111.

I moved wallet.dat somewhere else, and removed everything except cleanwatercoin.conf from my  ~/.cleanwatercoin directory
Removed all 'addnode=' lines and added
seednode=204.246.67.106:9340
(thanks doabitofgood.com)

Started up cleanwatercoin, and let it start syncing.
after a bit, I did:
cleanwatercoind getpeerinfo

107.170.217.4 was still on block 83111, and a couple others were not on the latest block. The rest were 84??? something..

Then stopped cleanwatercoin (well before block 83111), and changed cleanwatercoin.conf
to add connect= entries for all of the peers that were on the latest block..
Which resulted in:
connect=5.49.122.87:53591
connect=212.89.239.20:53591
connect=204.246.67.106:53591
connect=108.47.87.216:53591
connect=94.194.116.119:53591

Then I restarted cleanwatercoin-qt and it successfully synced to the latest block.
Stopped it again, removed the connect= entries, put my wallet.dat back, and it's all good...

Good luck,
