Engine won't start unless I manually feeding fuel.

Fuel filter changed.

Ran power directly to fuel pump and it doesn't make a noise. (Does it whine while on?)

1. How do I change this thing? Remove water line and then unscrew and go?
2. What will happen when i disconnect the water line? (water go splash)
3. What will happen when i disconnect the fuel pumpy? (fuel all over?)

2000 Mariah v6 mercruiser carb

Also, is the part # 861155A3?

If you can't "feel" it working , or hear it , it's more than likely locked up. Seems trash in fuel system is usually the culprit.
The pump is a fairly easy replace.
Unplug wire harness , remove inlet/outlet lines and remove from mounting bracket.
Being your old pump isn't working , should be little if any fuel leakage.
What water line are you referring too? The line from the fuel filter/water seperator unit maybe? Again , little to no leakage should happen.

thanks my good sir.

I was worried about leaking all over my waterproof boat...

I asked about the water line because it is in my darn way

Ahh , always something in the way huh!
Throw a towel under it in the bilge just in case.

You mentioned you changed the fuel filter. You do know that there is (or should be if someone hasn't removed it) another filter in the fuel line right next to the carb...right? Its nothing more than a screen but it can get clogged up too...

This is why i ask for the knowledge of the internets. I shall frackin the super secret filter

Just in case anyone comes here. THis fixed my issue of the engine not running. It was the fuel pump.

Easy change. Just takes patience and a 6 pack
