I am helping my neighbor get his motor running on his 94 tracker with a 1994 Mercury 90 OB. He has been through a very difficult time so funds are a bit limited (which is why we are not just taking it to a shop). My background is Aircraft but Im helping him anyway.
We can start his motor and it will run if we keep hit the electric prime on the key (doesn't seem to skip). My first thought was that the carbs are in need of some cleaning\rebuilding. I decided to open the throttle (using the button in the center of the throttle to disengage the transmission) a bit . I can get it to run very smooth at a higher RPM for a few min then it will sputter and stall.
Checking the primer bulb post stall it is still hard so its not running out of fuel in the tank lines.
So I am questioning my first thought and thinking fuel pump.
Reasonable ?
Due to his limited budget I don't want to throw parts at it. (the flip side is we don't have the tools and reference books a good marine mechanic would have)
