    Water pressure question

    I recently purchased an '86 70hp Johnson. I hooked it up to my old 0 to 15 lbs. water pressure gauge. At wide open, with the motor down, the gauge is pegged above 15#. With it jacked up, it maxes at 15# WOT. What is the pressure range for this model?

    tilt trim system flush?

    I have an '86, 70 HP Johnson with factory tilt/trim. It had a bad tilt/trim motor and I replaced it. Anyway, the oil is a milky tan color like it has water in it. Is there a way to change out the oil without removing the entire unit? The unit works, just don't want to damage it.
