any info on raw water pumps for 7.4 merc bravo 3 would be great. Put new housing and impeller on July 7 2018 ran it a couple hours. did not use boat at all in August. This past weekend used it on Saturday 9 1 2018 ran about an hour all was fine. started it up Sunday morning made  it about a mile and motor got hot. Took pump apart and impeller is trash no fins and is just a hub. Any ideas? New pump was a Sierra 18-3150.
