installed a new high pressured pump in a 150 merc yesterday it showed 5 on the psi gauge , today it shows 0 . did I burn the impeller up. No water comming out the pee hole. thank you,.
You probably will need to drop the lower unit again and check your work. Could be that the water tube is not in place where it goes into the block. Make sure the slinger at the water pump tube is in place.
I am sure others with more experience will jump in here to help.
