I have a 87 evinrude 150, I was wondering how i can tell if the oil is being pumped to the motor. It has an audible alert that is supposed to let you know if the motor is not getting oil but I don't know if it is working correctly. When I tried to prime the bulb for the oil it won't depress. Like it has already been primed. Should the motor smoke a little if it is getting oil? I am used to mixing my own oil on my old outboard so that may explain my ignorance Thanks in advance for your help
