Hello,
i wants to drain my Engine (Mercruiser MAG 350 MPI 5.7) for the winter.
I can find one Drain Plug in the Distribution Housing, one in the Thermostate Housing and one in the Gen 3 Cool Fuel Module. But are there two more at the Sea Water Pump? I cant find them. Are they behind the Cool Fuel Module?
If there are no more Drain Plugs how is it possible to drain the Mater Pump.
I would be very happy about your help.

I would eliminate the "Quick-Crack" drain system and go back to manual drains on the block and manifolds.
Depends on youir type od raw water pump , some dont have the drain feature and you must remove a lower hose .
 
Me too. The more complicated things get, the more chance of an expensive screw up!

The ordinary marine V-8 has 6 drain points: both sides of the block, the manifolds, and the risers.

Ok, I think thats all to complicated.I think i will rinse again with antifreeze over the z-drive.
Thank you for your help.
