A boat primer solenoid is an electric valve that allows fuel to pass through and be injected directly into the intake manifold, effectively bypassing the carburetor. When voltage is applied to the solenoid, a steel rod opens the valve, allowing pressurised fuel to pass through. The primer solenoid is just a valve; the pressure comes from either the primer bulb or the fuel pump. If the voltage is okay, you can remove a primer line from the fitting at the carburetor of the intake manifold, pump the fuel primer bulb up hard, key in the RUN position, and push the key in.

The primer solenoid is an electric valve, not a pump
The solenoid is an electromagnet with a steel rod in the centre. When voltage is applied to the electromagnet, the steel rod opens the valve that allows pressurised fuel to pass through and be injected directly into the intake manifold, effectively bypassing the carburetor. The primer solenoid is just a valve; the pressure comes from either the primer bulb or from the fuel pump.
In earlier engines, choke plates activated by solenoids closed the carburetor throat to block airflow and force the pistons to pull more gasoline into the intake. This enriched the fuel/air mix, making it easier to start a cold engine. Either primer solenoid or choke plates enrich the fuel/air mix and so do the same thing.
If the voltage is okay, remove a primer line from the fitting at the carburetor of the intake manifold, pump the fuel primer bulb up hard, key in the RUN position, and push the key in. Fuel should shoot out of that disconnected hose.

The primer solenoid is just a valve; the pressure comes from either the primer bulb or from the fuel pump. If you are not cranking the engine, the fuel pump does nothing because it relies on the movement of the pistons.

When the electric primer solenoid is activated, it opens a passage and fuel goes into the intake area
The primer solenoid is an electromagnet with a steel rod in the centre. When voltage is applied to the electromagnet, the steel rod opens the valve that allows pressurised fuel to pass through and be injected directly into the intake manifold, bypassing the carburettor.
The primer solenoid is not a pump, but a valve. When you pump the primer bulb, you create pressure in the fuel lines and fill the carburettor bowls. When the electric primer solenoid is activated, it opens a passage and fuel goes into the intake area. This fuel primes the motor. If you don't re-pump the bulb or start the motor, no more fuel will flow through the open valve.
The primer solenoid is similar to earlier engine mechanisms, where choke plates activated by solenoids closed the carburettor throat to block airflow and force the pistons to pull more gasoline into the intake. This enriched the fuel/air mix, making it easier to start a cold engine. The primer solenoid has the same effect, enriching the fuel/air mix.

When you pump the primer bulb, you create pressure in the fuel lines and fill the carb bowls. When you activate the electric primer solenoid, it opens a passage and fuel goes into the intake area. As you lose line pressure, the fuel quits flowing. That fuel primes the motor. Without re-pumping the bulb or starting the motor, no more fuel will flow through the open valve.
