Hello jalbin0308, I may can help but "NEED MORE INPUT" said ET. Model, year, HP, ect.
SOURCE: Johnson Outboard Motor 175HP
Not knowing what year it is...Light and alarm? Reason: overheat low oil etc. check water flow..water pump. The motor is most likily going into S.L.O.W mode. its a fail safe system. Last possibile reason ..CDI box and or stator.. pull plugs check compression...should be 120-150 lbs.

Carbs probably need to be cleaned and re-built. Common problem in outboards that havent been run in a while

Ihave a 1991 70 hp Johnson outboard thats hard to start the first time but starts good after that. Seems to be flooded. Starting rpm seems to be low.
SOURCE: 1974 Johnson 70 hp outboard, quits on acceleration.
It sounds like your motor is starving for fuel. At an idle, you have adequate flow to keep the engine running. When you call for more fuel...you sputter and quit. Could be a clogged filter or trash in the line or in a jet. Yes you will have some air in the bulb, but not a great deal. You could be sucking air at a hose connection (loosing some prime)...try this, start the engine and slowly accererate, have someone pump the bulb as you accelerate, see if the engine works properly while doing this test.
