Did you clean out the pee hole with a small wire? Mud dobbers like to plug them up.

The pee line is definitely clean, that was the first thing I checked. Blew air through it. I even took the elbow piece off the top of the cylinders to make sure that wasn’t stopped up.

It appears that this motors exhaust is two holes mid ways up the back side of the motor leg. Idk if some water is suppose to come out that too but No water is coming out of that either.

I dropped the lower unit...again...replaced the impeller with a new one. Got it reinstalled last night but it was to late to test, goin to do a test again today after work. I’m thinking about getting a tub or bucket instead of using muffs. That way I know for sure it’s getting sufficient water.

if this new impeller isn’t the fix, I’m at a loss at what it could be.

Just one more thing to try if the new impeller doesn't fix it. Put a nozzle on your garden hose and shoot it up the water tube. If you are getting water out the pee hole then your water pump is malfunctioning or not hooking up to the outlet on your pump housing.

1992 FourWinns Horizon 200 20 ft - Impeller replacement Engine: 5.8 L V8, 1991 OMC Stern Drive I replaced the impeller a few months ago but when I started it up recently the impeller did not pump water and then melted from the heat of spinning dry.
I cracked the housing as well. I had the hose connected but there was no flow through the motor. I shut the motor off pretty quickly. It ran for maybe 1 minute, but I was too late !!
Am I right in assuming that it melted from spinning dry? Why didn't I get water flow to it to "Prime" the impeller? What can I check?

So I got it all reinstalled, still not getting water. It’s as if the drive shaft isn’t turning at all. Idk what to do. I’m at a loss.
