hydraulic lift

[slingshot]

have a cmc lift on my boat. It will trim up about enough to put my motor brace on but thats about it then it starts to bogg down almost like my battery starts to die[ I know its not my battery]. Don't know if I have lost some fluid or have air in the lines. Either way it looks like a sealed unit except where the 2 hard lines come out of the bottom. I see no place to add fluid. any ideas?

i have 2 CMC there is a place to put fluid in . the one i have it is at the top . a allen plug and there is another one on the side that is a fill line .standing behind the motor look on the left side .

If I find it, what type of fluid? anykind or is there a special kind for those lifts. Where do I find it.

this is the manul
think any hydrolic fluid would work like for jacks and such
