I am looking for help to trouble shoot an oil mixture problem I have with my 2001 Johnson 150 Oceanpro. I was out on my boat when my oil alarm sounded. I filled the oil reservoir with 2 cycle oil and my alarm continued to sound until my engine sounded as if it had no oil mixed with the gas and it ultimately shut itself down. Where is my oil pump located and how do I test it to see if it failed? Thanks
