More of the same...Is there some issue with quality control on these Mercury OEM parts?
I got the Mercury water pump rebuild kit
18-3446 - Water Pump Kit 46-70941A3
Got the mercury impeller Drive key 28-8M0032835
Was reassembling water pump and spent 30 minutes trying to get impeller into...
I just found a suggestion that says the "lip of the seal should be facing the outside" in an online manual. I've always thought that with an oil seal of any type the lip would face the contained oil, but maybe its the other way around
I've ordered the 2 linked Ebay listings. They are both OEM mercury. I am assuming/hoping that the bushing was maybe an off brand, and that these will fit correctly together
Man. It is tough with these old parts. I ordered a shiftshaft seal from marineengine. OEM part from the parts list(all attached to my motor by serial number). Got it and tried to install it in the old bushing>
I've never installed a shift shaft seal before. Tried to install using a mandrel...
Yeah.. Spent some more time with it, and it does go into reverse. Even with the shift shaft in without bushing or anything, its a little finicky. Sometimes it just doesn't want to go. I'm assuming maybe thats a worn out part of the gear box or something.
Hopefully when I get the parts I can get...
It did shift into reverse before when I was using it, so I am assuming that is still the case. So if I'm able to get the shift shaft into the cam that is correct? I've never done it before. Trying to PASA(plan ahead, stay ahead) for when I actually resinstall in a week or 2
OK. I'm assuming this should stay in this topic.
Still waiting for water pump to arrive. Shift shaft oil seal is leaky, so removed shift shaft and ordered a new seal and O-ring.
Since I have some time before it arrives, I messed with trying to get the shift shaft seated again on the cam...
I am currently traveling for work, but plan to install the new waterpump when I'm back. Im getting concerned that, though the waterpump i installed might not be perfect, it is working, and that makes me think that the issue would be somewhere else.
To this point I have
-rebuilt water pump and...
I also seem to have an oil leak coming from the shift shaft. I don't want to throw any more money at this until I figure out the coolant issue(hopefully solved with new waterpump).
I know I won't know for sure until i take this apart, but do the bushings tend to hold up? Would a leak typically...
by your definition it seems that the impeller/pump system is a bit weak.
I was getting water, but nowhere near what he was getting. I'm including my video for reference. Looked like about 4-5" max.
I also tried blowing air into the water tube and did get air coming out of engine block...
I was hoping that was the issue. I'm not getting enough water through the top spinning the drive shaft as in the video.
I'm gonna rebuild waterpump again. Ordered an OEM part so should be able to use the base as well.
I just can't figure out why the water pump isn't pumping enough water. the...
Just to make sure I'm clear, the impeller isn't sitting it the middle of the waterpump. As it spins, one side is closer to the side walls. Is this what you are saying? I guess my assumption was that the impeller would have the fins equidistant against the walls of the water pump
I wanted to send an update if someone is in s similar situation.
There is a great troubleshooting video on how to check through issues with lower unit. In my case, pump in new waterpump and impeller, spun it on drive shaft, and then installed, but wasn't getting much water up through the engine...
It is. Thanks. short of repeating the steps over again, I'm a bit at a loss.
The only thing i can think of is to connect a hose to where the water guide tube connect to the tube that goes to the engine. I don't know the exact schematic of the coolant system with the motor. Maybe somehow through...
I did check compression. I don't remember exactly what it was, but right around 120 on both cylinders.
I've never had an outboard overheat, so I don't know how severe it was, but if the plastic washer had melted, wouldn't that prevent the water from running through the system? If tried...
