My 40hp Merc single ram 2 wire trim/tilt unit won't raise under load. Raises fine out of the water, But you can push it back down by hand. Can someone tell me how to check the fluid level? Or point me in the direction of what else could be wrong with it. It has 2 screws/plugs that I see on the outside of the system. One large black slotted plug and a white yellowish plastic plug. And on top what looks to be a bearing Bleed valve. Any help would be great!
