It sounds like the high speed passages in the carb are gummed up. If you have not done so already, you should probably rebuild the carb.

Impeller is at the bottom in the housing. it may take a few mins for the water to come out of the tell tale hole. Ensure that your muffs are on properly and wait for a bit. Also insure that the hole is not plugged.

My Mariner 8 has a thermostat fitted. It only pumps water when it heats to normal temp.
If your engine stops, it may be a fuel problem. Check the plug and go to Marine Doctor (a) fuel diagnostics, (b) spark plug diagnostics, sections. PK
