    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to 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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    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...

    '85 7.5hp, rebuilt water pump. Still issues with water flow to engine

    Hello all, End of last summer was out fishing, using kicker and it started smoking and stalled. Didn't see it, but was not peeing correctly. Started messing with it this spring. Motor works fine. Good compression. Figured there was probably salt buildup in water lines. Flushed out all...

    59 Glasspar Seafair sedan possible transom rebuild?

    I rebuilt the transom myself, and it has held up well to this point. No stress cracks or anything to indicate any compromising of it. I relocated the batteries to the cuddy, got rid of the side saddle aluminum tanks and put my tank behind rear seats. I will look into the Suzuki.

    59 Glasspar Seafair sedan possible transom rebuild?

    Hello everyone, I inherited a very old and broken 59 Seafair sedan in the classic way that many of us do, through the promise of a working boat that was far from. After having it for about 6 months, and realizing that it was in bad shape, I decided to rebuild it. Having zero experience with...

    Hello, I have an '85 7.5 that i use for my kicker motor. I am needing to replace the throttle cables as mine have rusted out. I have a Seloc manual, but it has almost no info on disassembly/reassembly for the tiller arm (Not a fan of these, but could not find a Merc version for this motor). I...

    measuring float levels on mercury carb

    Hello, I have been a bit confused on this for a while so have been trying to split the difference. On adjusting the float levers it has measurement D at 10mm. I am a bit confused as my carb top has a lip and the diagram does not. If i measure from the top of the lip, the top lever is exactly...
