I have a 1993 Carb 150 Evinrude Intruder that Im having fuel related problems with. When I prime the primer bulb the motor will run good for approx 2-3 minutes. Then you will here a ticking noise and the engine will begin to run rough and eventually die. Almost like it is starving itself of fuel – would this be a fuel pump? I eliminated a clogged fuel filter by putting a new one in.Thanks

It sounds fuel related and would be a start. The fuel primer bulb sould be our first look. An inexpensive replacement item.

If I continue to prime the bulb the engine will run smooth – so could that be a primer bulb. There is a pretty loud ticking noise coming from the fuel pump area.

Put some oil in the fuel also in case it is the VRO Pump. 50 to 1 on oil for safety sake. Then put a new primer bulb in. It is either the primer or fuel pump.

I had same problem with 1995 Johnson Faststrike. My motor was also hard to start. I replaced the VRO pump. This fixed my problem.

Sounds like the VRO pump to me too. I relaced it with a fuel pump and just mixed my oil…no more problems. (91 Faststrike) I fished a lot during cold months and the oil pump is just a diaphram on those motors, I just didnt want to take the chance that it might fail trying to pump that thicker, cold oil. The fuel pump is a lot cheaper too. Or at least at that time it was. Good luck!
