I noticed water dripping from the weep hole on the water pump and made the decision to purchase the rebuild (bearing and seal ) kit on Amazon for about $65 and do it myself. At the time I noticed the weeping, the engine was not overheating.
I made the decision to "down" the boat and rebuild the pump before there was a more serious cooling problem. I also thought that it made sense to replace the thermostat at the same time. During the installation of the new bearing, during rebuild of the water pump, I lacked the correct size pipe to tap the new bearing into place. I used a slightly smaller pvc pipe that resulted in some deformation of the metal seal covered in rubber that covers the actual ball bearings. I removed the bent metal seal, added some grease to the bearings for good measure and proceeded with the rebuild. I manually rotated the the pump and did not notice any unusual resistance.
I reinstalled the pump and reconnected hoses. I ran the engine on the hose using the flush port on the starboard side of the engine for at least 20 minutes. The temperature was stable at about 140 degrees on the gauge. I attempted to use the boat today in the warm salt water. The water temp at the ramp was about 90 degrees. Outside air temp was about 92 degrees. I warmed the engine at idle while tied to the dock for about ten minutes. The engine temp gauge was reading a stable 150~160 degrees. We left the dock and proceeded to depart the marina area. The engine temp (at gauge) began to gradually rise and stabilized at about 200 degrees when I made the decision to return to the dock. We never left the marina and we never went above the slowest idle speed possible. The entire duration of our short ride, from departing the dock to returning to the dock was about fifteen minutes. I quickly touched the water hoses at the thermostat area and also quickly touched the manifolds. The water hoses felt pretty hot and the manifolds felt warmer than usual. We returned home, allowed the engine to cool completely.
This afternoon I attached the ear muff flush to the outdrive, disconnected the water hoses from the water pump, and with the engine off, turned the water on full open at the spigot. No water exited either of the water hoses that were attached to the water pump.
I have ordered a new water pump rebuild kit, assuming that the damage I caused during my first rebuild experience may the culprit since the engine was not overheating until I had the great idea to fix a problem that was developing before it was really a problem.
Any assistance or advice would be greatly appreciated.
Thank you!
