Default Water in 4.3 Mercruiser cylinders

I have no water in the oil if that provides any helpful information.

Thanks again,
Trey

After slowing down rapidly water rushed into my engine because (i
think) the exhaust flappers are failing to close or are missing. This
is a 97 Dynasty.

Removed the plugs and got the water out. Starter seems to have been
damaged since the engine was locked but I did get it to start again to
try to evaporate the remaianing water droplets in the cylinders.

After I replace the starter and exhaust flappers will I be good or is
there a lot more damage to my engine?

Thanks for any responses.

If you had hydrolock, the starter just moaned, you may have bent the push
rods, and blown the head gasket.

Get the water out asap, start it up, then let cool down and check
compression to see what, if anything happened to the head gasket.

You should check the push-rods.

I have a merc 5.7 with the same problem and almost every rod is bent, and I
had to replace the head gaskets. I still run it but very carefully, as I
have to pull the engine to get to the flappers.
