Just a suggestion for the future if you don’t have a setup for this. Get you one of those goofy looking sockets they show on TV that is suppose to fit any size shape fastener. Next time you have an over heat or water pump issue use it to drive the driveshaft. Get you a piece of copper tubing of the proper size and length to fit the pump grommet. Bend the top of the copper tube away from you (experience). Put the gearcase in the tast tank and run a drill motor. You should get a healthy head of water at the end of the tubing. Keep in mind the drill may not turn the water pump as fast as the motor will idle, but should be close enough to simulate. Just another way to separate different systems on the engine to figure out what your problem is. Be sure and pick the gearcase up high once it primes. Just keep the pickups under the water to see how it reacts.
