    Default Mercruser trim tilt problems

    HI I have a trim tilt that runs for a few seconds and stops, I jumped the relays to see if the pump would continue running because I was told that would bypass the wireing and test just the motor and the motor still runs for a moment and stops .so I'm wondering if the motor is bad it sets for a few about a minute and will do it again I was wondering if it is acting like a coil and shorts out as it warms up thanks.

    take it apart and clean the armature check the brushes for free movement and it should work just fine.

    1. The only Maintenance I see for the power trim, according to the manual(s), is air bleeding. It makes sense to me with no boat history after 15+ years to begin to change the fluid that appears in reservoir tank 2 or 3 times a year, or disconnect lines, in order to change all of it (same applies to power steering?). Best way for change?
    2. Also, I can search the Internet and I think I looked in Service Manual 32 but what happens if the power trim fails at the ramp? Do I need to start carrying tools to disconnect power trim lines? And, if I'm strong enough to pick up the drive, then what? Trailer clips?

    1 basic maintenance for the pump is keep the water out of the oil .Unless its milky, just maintain the level.

    2 Try to not let that happen . If it does you can remove the 2 lines at the pump, tie a rope around the prop and pull up and tie off, messy though

    Remove the nuts holding the rams to the drive, tie a rope around prop, raise up and tie off
