I am working on a mercury 4.0 hp and I’m trying to find a carb and impeller for it. Serial number is 9118728.

Rebuild current carb with a factory rebuild kit, don't use aftermarket parts unless you want to do it over.

Do you have a link? Also what about an impeller.
Not a computer wiz here, to old to learn ! But there are numerous places that have oem parts. Crowlie's if I have the name correct is a popular place. I use my local marine parts supply store, it might cost a few bucks more....but they have the parts in stock most of the time, give you tips on installing the parts, and can answer your questions as the counter folks are prior hands on mechanics ! Those little things can be worth their weight in gold when a problem arises !

Gee, change the engine oil if a 4 cycle motor. Change the gear oil and clean the carb. Run her a bit and then rebuild the waterpump.

Running the at Serial # brought up nothing. Is it a US motor, or a Canadian, or an Australian Motor?
Is it a Single Cylinder, 2 Cylinder, a 4 Stroke or a 2 Stroke
