Yamama 30D two stroke power tilt and trim

[eyespy999]

Hi I have a PTT on my 2001 30d engine. It has been working perfectly until recently. When out of the water and on the trailer I can tilt it up and down without any issues. When in the water and trying to tilt down whilst under power it is starting to screech. Only appears to be happening one way. I have not checked the hydraulic levels yet as wanted to seek advice first before I fudge it!
Thanks

Power trim on a Yammie 2-stroke 30D... now that's pretty rare.

Raise the engine on the level (support it as a precaution), then undo the filler plug on the power trim. You can top up with Yamaha Power Trim Fluid or Dextron II ATF. Use a little marine grease on the ram seals. If the screeching persists it may need new seal kit.

Great thank you for the advice I will get on to it today.
