Model #65373R
This is my dad's boat, but I've been tinkering with it to get it back to life. Haven't had to do much, so far. The boat and motor are almost like new. They've been sitting in a barn most of their lives, having only seen water a few dozen times. The motor was last run 7 years ago, before I started messing with it. Before turning the key, I replaced the impeller. Then after some troubleshooting replaced the rectifier, starter solenoid, and thermostat. I kitted all 3 carbs as well. I also had to replace a broken stern bracket (trailer tilt on these motors is the dumbest design I've ever seen).
The point of my post is that after replacing the water pump, I can't seem to get water to pump out the exhaust relief holes. When I run the motor on the muffs, I see the water being pumped out of the rubber grommet that the shift rod passes thru. I have dropped the LU 3 times to verify that the water tube is inserted correctly into the water pump housing. At first I suspected a bad driveshaft seal, or grommet on the pump housing. I tried to remedy this by buying an OEM water pump repair kit w/housing. It came with all new seals. I put it all back together, and still the same thing. I thought maybe running on the muffs wasn't a good test, so I took it to the lake. The motor occasionally spits water when running it on the lake, and it never feels too hot to the touch. I can hold my hand on it for about 5 seconds before it starts to burn. I've watched Youtube videos of this motor running in test tanks, and they all spit water continuously. I backed the boat in the water on the trailer just deep enough to cover the section of the motor housing the water pump, and I could see the water spewing out the shift rod grommet still. I don't know what else to try. This last time I reinstalled the LU, I had the motor tilted all the way up so I could see the water tube going into the pump housing, so I'm pretty sure that there is a good connection there. Does anyone else have any experience with this motor that could point out something that I'm missing? I would take any advice at this point.
