OK. I've been trying to find the "fill" hole on my tilt/trim, but either I'm blind or don't understand how the system works. The only opening I can see is a thumbscrew w/a phillips head on the starboard side of my hydraulic cylinders. I cracked this SLIGHTLY yesterday and fluid seeped out. It is in the horizontal position and I can't see how to add fluid without having the fluid that is in there run out in the process. What am I missing? Anybody got a pic of the fill hole/location?
