I have a 1989 Regal Ambassador 233xl with the 5.7 Mercruiser and what I have been told is, the usual trim pump. I am experiencing a "grinding noise" that only happens when I trim "down". At times the noise is low and at times it is high. This "grinding noise does not happen when I trim up or trailer up. The tank was low so I did refill it, however the noise remains the same. Does this sound like an air in the line issue or is the pump shot? If it's air, how do I bleed the system?
