I need help with my mercury 15 hp 4 strokes engine. It leaks pretty bad. I thought it was fuel pump or carburetor or clogged jet but turn out it just leak.
The engine started fine when I first prime the bulb to get gas to engine.
Disconnect the gas supply tube and I see a lot of gas shooting out while engine running so I guess the fuel pump is fine too.
here video of the leak, not sure what part or gasket I need to fix this leak.
