I have a generation 4 7.4 motir im getting ready to stop in my 1990 sea ray sundancer. Before putting it in I decided to prime the oil pump by installing my primer in the distributor hole & priming it that way. It did get up to 64 psi on my gauge until the drill bogged down drastically. I pulled the primer out & noticed that when I put a screwdriver down on the pump shaft that it is really hard to turn. Shouldn’t it turn pretty easily?
