trim tilt makes noise when press button but wont move motor

[marine11]

I have a 70hp mariner 81ish model with trim and tilt, although when i push the button up or down there is a lot of noise as if it is working although there is no movement of motor at all.

is this motor stuffed or do i need to bleed it or top up with fluid, how can i check if trim motor is stuffed.

thank you

See my answer to your solenoid post, Marine11. One trouble is causing both symptoms.

Have you checked fluid? And is the manual release valve off its seat?

The manual release valve is on the side of the transom bracket. I can't remember which side but it will be recessed and has a flat head screwdriver head and is plastic. Turn this out lightly until you feel slight resistance. Pull up on the lower unit, put trailer lock down to hold up lower unit. Check the resevoir for fluid. If fluid is pink in color it has Dexron II or III Automatic Transmission Fluid if more clear it is Power Trim Fluid in it. Fluid level should be level in the resevoir. The resevoir is the cylinder looking compartment without any wires going to it. This will be messy so have a big tray to catch oil.
A normal size oil pan will not catch everything, if you have to add any fluid. If you have to add any fluid you will have to cycle the PTT up and down a couple of time. On your final time if it works leave the drive in the down position for about 20 minutes to let air bubbles break apart in the resevoir. The only way to check fluid is in the full up position!
