Dave, I pulled my old mark 10 out today and took a picture of the port drain or whatever you want to call it. Just make sure it is NOT plugged. It brings water to the impeller and it also drains water away so it don’t freeze up. I got lucky and my motor froze and it pushed the gasket out that covers the shifter paws so it didn’t hurt anything. I later found out why. Hope you get her going, warm weather is coming, so they tell me!
