Your rpms seem way to high and even more way too high considering the speed...
A basically stock PRO with the 1200 ought to be somewhere in the low 60's with rpm's in the 6700ish range on the stock prop...
I would suspect a pump area issue somewhere...Perhaps you're sucking air allowing it to spin way up in the r's but not get the speed?
