If the fluid is pink,then it's trim/tilt fluid.
Brown it's probably 20 or 30wt. Motor oil.
To remove just the body? You need to remove all 4 hydrolic lines.
Then 4 phillips screws.
It should just drop out if all is removed.
To remove the whole thing? You need to remove the 4 lines and the 3 mounting bolts.
Then undo the power cable from the relays.
Then you can take it apart from there.
Reassembly= Take your time and DON"T cross thread the lines.
To fill I use an old style oilcan.Filled with either motor oil or trim fluid.

Just realzed: the 91 is a 90 or 120. 85/125 were older models.89 was the last year for the 85.
Any ID on the motor? Pics help.
Yes oil will come out.The T/T fluid can be bought at any marine place.
Profile,location? You might be close to someone who can help??

use non-detergent motor oil on a 89-92 3ram trim system with prestolite pump. If the fluid is too thin then the engine will bounce when lowering. I had thought about changing fluid in the shock dampener to correct this but stopped doing force system repairs before I ever figured out the details.
