Tilt/Trim hydraulic fluid discharge

[tgell001]

2010 Stringray 180RX, 3.0L Volvo, SX-A outdrive.

So yesterday when pulling the boat out of the water my buddy trying to be helpful "raised" the trim for an undetermined amount of time after I had already raised it and I noticed an oil slick in the water behind the boat. Asked some questions, figured out what happened and once it was out of the water I lowered and raised it a few times and it seemed ok on the way down but while coming up when it hits the upper limit it shoots oil out of the side of the outdrive housing like where it meets up with the transom.

Once i got it back to the house I went up and down a few times and it will go up and down but the pump motor labors in certain spots and I feel it wont go all the way up though its hard to measure whether that is true or not.

My question is..... Is the discharge of oil a design feature to prevent damage to the pump or did I blow out a seal or hose? and, is the labor of the motor simply a result of being low on hydaulic fluid since i discharged and bunch of it? The place the oil was coming out of was a hole but i'm not sure if that was the purpose of the hole.

Ayuh,.... Yes, you have a Leak, that shouldn't be leakin', 'n Yes, it's no doubt gettin' very low on oil...

Ok so i investigated this problem a little more yesterday evening and I found the spot that its leaking. Theres a 4 way manifold at the transom thats i'm assuming means theres an up and down for each of the two pistons and a control valve. If you look at the exploded view its the "A" connection that mates the pc 9 hose with the manifold. I leaning towards the leak being caused by the "o-ring" (pc 8)

How is the connect at this manifold made? is it something standard that can easily be worked with? Also, once i've replaced the oil in the system is there a procedure for bleeding out the air?
