Mercury 115hp/Tilt Bleeding Proceedure 1983

[Steel120]

I have an older 1984 mercury 115hp in-line six with the seperate trim motor assembly, four hose type.

Everything is currently working, however, the hoses are in need of replacement(white braid showing, one is leaking). I have ordered the hoses, sierra 18-2110 and 18-2111 2 of each.

My question, when they are replaced, what is the correct proceedure for bleeding the system? Sequence for bleeding?

My hyd. cylinders appear to have two hex screws at the top of each, one is smaller than the other. Are these the bleed openings?

Unit uses standard sae 30 oil for fluid.

If anyone has suggestions or needs clarification, I will answer quickly, and could also supply photo's if required.

searched the board, but could not find any specific directions.

Thanks in advance Bob

The system must be filled with the engine tilted up

Hope this helps

ive done repair on tilt trim before and it is better to fill the reservoir with the motor in the raised position. Run it up and down a few times then bleed the lines and then make sure after you bleed the lines to refill your reservoir and all is good as long as the pump isnt shot. Air in the lines is the hardest thing on them and water keep them both out k good luck!
