Location of drain plugs???

[g-cando]

I took my water drain plugs out last fall. I am putting them back in and I am going nuts. I have 5 out and can only find four holes to put them in.

I have one on each exhaust manifold (2), one on the right side of block (looking from waterpump) low by oilpan, (1) and one on large hose leaving waterpump at middle of right side motor. That is four and I am holding one in my hand. Cannot find hole
Sounds like high school prom.

I could start it in the water next week and see where the water comes out. Ha ha

I have a 1997 Mercruiser 5.7 liter 4 barrell Thunderbolt.

Any help will be appreciated.

Look on the starboard side of the block above the oil pan. That would be the left side looking from the water pump.

I have looked there. There is a temperature sensor near the back.

It's not a temp sensor, it's the knock sensor. It's in a tee.
