Hello Allen. My name is Tan.

Those are exhaust ports. Especially on the hose as it falls down the exhaust housing and out the prop hub.

Water usually doesn't come out those ports till you are running at full throttle. Long as you have no alarm the engine is fine.

When was the last time you had the water pump serviced?

Expert:  Tan replied 1 year ago.

The holes are circled in red. Are these the holes you are referring to? The blue circle is where the majority of the water flows out on the flush attachment. When engine is in the water you will get some water out the top ports but mostly at higher rpms.
