1977 140 johnson water pump question

[Dylan's Dad]

Ya'll have probably answered this already from some of the post iv read but need to be sure .
I replaced the impeller with a complete kit ,housing ,stainless bottom plate, the stainless cup, I noticed it did not have the rubber seal on top of the impeller housing and shifting rod when I took it apart that came in the kit which I installed ,when i went back together with it ,I also replaced the bottom two exhaust gaskets .
I crank it in a big clear storage bin I got at wallmart ,which is just the right height that my whale tale sits on it ,when full of water the seam is above the water, where the upper half of the lower unit and gear case meet.
when I cranked it water sprays out of the three holes in the front of the lower unit 2 point down 1 drilled on each side of the shifting rod cover that are coming out the stabilizer fin and 1 that points straight out toward the boat right at the seam ,these are spraying pretty good and i dont recall them doing this before .
i have been looking at some of the other post and hope its because i have the seals in it now between upper half of the lower unit and the pump, and shift rod ,also new exhaust gaskets ,giving the water no other place to go , and that this was suppose to have been doing this all along .

Thanks

Is the water spraying out the holes on my motor normal ?

you are better off using muff on that motor. i have the same one. it leaks all over after water pump change.

There are two drainage cavities just outside the shift rod cover that should have small holes; water should run from those. When the engine is running, excess cooling water fills the outer section of the midsection and should drain from any of the drain openings at the top of the gearcase. Also, there is also a small drain at the bottom front of the midsection.

If the water is excessive, or badly fouled, the exhaust gasket may be misplaced.
