    Thank you for your prompt response to my inquiry.  Yes this alarm is usually after multiple short runs at low rpm.  For example after drift fishing and short runs to adjust position.

    I have previously checked the oil reservoir pick up filter and it is clean and no apparent blockage.

    Per y0ur suggestion I am going to draw a vacuum on the pick up hose from the reservoir to the oil pump manifold and see if my Vac. gage holds over time.

    I will also check the short hoses at the engine for leaks as best as I can.

    You mentioned the Tach/Gage reliability, would this failure be identified by a specific code in the diagnostic test.
