      Hey guys,

      Recently purchased my first mercury, a KE7. Im used to working on OMC’s and am not used to the mercury designs. I am trying to remove the lower unit but cannot figure out the proprer way. I have loosened the nut that sits above the prop, but do not see anything else on the exterior that can be removed. Do have to diassemble from something behind the impeller houseing and move on from there? Any help would be great, Thanks

        Jeff,
        Pull the powerhead to get at the other nut. Long bolt under the engine if memory serves me well. Check the waterline tube for being clear too + impeller. Anyone recall if this tower has the anti vibration piece like the KG7?
        Why are you removing it ? Only 6 bolts & comes off & find a new powerhead gasket please.

            Awesome, thanks! I’m taking it apart to clean out the waterline and regresse if necessary and to change the impeller.

            Thanks again!

              lower does not have to be removed to do that. most of the time the water tube is frozen into the lower and will cause you problems to remove.. just remove the powerhead to access the water tube top . remove the prop then the water pump cover for the impeller. if you need to the water pump cartridge and prop shaft and gear will come out as an assy.1 914 310 7086.

                      Good morning, I live in central Kentucky and I am wanting to know of there are any members within a few hours drive that have the special tool to remove the water pump plate on a Mercury KE-7? Replacing the impeller is one of my last tasks before I put in the the test tank. I know that the threads are left hand but I haven’t had any luck with getting the plate off. Thanks.

                        Try going around the outside of the cover with a hammer and a drift a few times
                        to free it up.. That has worked well for me.
