I agree with the last post check to see ifit was installed right the fins of the impellor should only face one was and make sure the key is in place on the shaft of the impellor. im sure your using a new impellor cause if your not the rubber could have sepperated fron the housing

Your description of what it does sounds like the Sierra pump we 1st used on the Johnson tried on my '84...wound up swappin' it out for a real factory replacement which solved the problem instantly...no more off brand pumps for me...

ditto reel, had 2 sierra's go bad within 2 weeks, went with merc's and all was good. also learned to change out the housing along with the impellor.
