I just got a 1990 force 90 hp boat. Theres no gas getting to the spark plugs. i have rebuilt the carburetors and cleaned the fuel pump but there is still no gas getting to the spark plugs. I’m just out of ideas of what it could be so any idea helps. Thanks.

Choke is working ?----You are operating choke switch / pushing key in while cranking it over?

" i have rebuilt the carburetors and cleaned the fuel pump" Cleaned the fuel pump? Did you check/replace the pump diaphragm?

Are you 100% sure that carburetor bowls are full of fuel , yes or no ?

You holding the key in as you turn it over?
The key needs to be held in, not just pushed and released.
You have the old style choke or the newer primer system?
What's the compression?? Spark on all 4?

The 90 HP would be a 3 cylinder I think.-----Spray some mixed fuel into the carburetors while cranking it over.----That should offer you a clue as to what is going on.------If it does not bark at you , it is not a carburetion issue.-----My bet is -----NO SPARK----at the plugs.
