You need to run those JW motors at 16/1 for sure, they need the oil. Just a guess, is your impeller housing worn out? How about the stainless wear plate under the impeller, is it grooved out? You can pick those up on Ebay sometimes for a reasonable price. Running in a barrel may not allow the motor to cool properly either, since your cooling system water is aerated with spent exaust gases.
