DF50 Power Trim

[perkrim]

Trouble with power trim. (newbe)
When raising motor, before mooring, tilt mechanism works fine 70% of the way. During the last 30% the tilt motor is intermitting.
I suspect low level of servo-oil.

First:
Can somebody tell if I'm on the right track or way off?
Secondly:
What kind of oil is correct? (full spec.)

Yes sounds like it is low on power trim and tilt (PTT) oil. You can use PTT specific oil or automatic transmission fluid.
