2017 Mercury 40 HP Water Pumping LIne Problem

Today went out for a quick run to pick up a couple crab pots. Got about 1/4 mile from the dock and motor shuts off unexpectedly. Thought I caught a old crab pot string or something.

Turns out water pump hose that shoots water out engine had a large crack in it and all the water pumping out was being pumped inside the engine cowl. Never noticed it not pumping out when we left dock.

When I removed cowl a good gallon of salt water poured out. Engine would barely turnover or do much of anything. Definitely not sparking. A near by boater helped me back to the dock and I loaded out.

Back home I rinsed everything off inside the cowl and coated in water repellent spray.

Motor still wont turn over much or start but makes noise.

Wondering what damage I have done to my engine???? Help, engine is only 3 years old and been very well maintained.
 
Did you crank it over with the plugs out to expel the water? Also, IF this is a 4 stroke, did you change the oil?

I went out first thing this morning took out all four plugs and turn the motor over. Put the plugs back in the motor. Still not getting much crank over. Going to go change the oil this morning when the store opens up
