Yet Another Fuel Pump Question

Sorry, I know fuel pumps are a hot topic but I have a basic question:
1997 Prostar 190 Indmar with the inline fuel pump mounted at back of motor:
Boat is not starting. Strong battery and turns over fine.
Not seeing any fuel sprayed from throttle bodies. Has new fuel filters and has gas all the way to the fuel pump. I unhooked the fuel line on the outlet side (I.e. Carburetor side) of the pump and turned on key. Fuel pump spun up and shot a little gas out. But, once I started turning motor over, no gas came out at all.
So...basic question: seems like it would be shooting gas if working properly?
Thanks in advance.

You could disconnect the fuel line from the carb and crank it and if it keeps pumping fuel out it should be good . Check your tank and see if the screen on the pickup tube is clogged , make sure your fuel lines aren't kinked.

I actually disconnected the fuel line on the outlet side of the fuel pump and nothing is pumping out when I turn over the engine. Guessing that means bad fuel pump, huh?

Thanks, completely overlooked 88falcon's recommendations to check filter and fuel lines. Will do.

OK, so I am getting good gas delivery to the intake side of the pump but nothing out the other end when I crank it over. Pretty well indicates the pump I suppose. I know these pumps are hard to find and expensive. Any recommendations for a source are appreciated

Did you check the screen on the inlet side of the pump? This is known to get clogged.
