I have a Hydraulic Place Diverter leaking from the piston cylinder shaft.
Is there a way to replace a seal, and if so how does it come apart.?
Or do you you have to just replace it?
Just need the Hydraulic piston assembly .
If needed where would one find one ?

Also do the Hydraulic Lines have to be bled or not?

I appreciate all your efforts in describing what to look for however, if I could find someone that has successfully installed one of these relief valves  on a Dominator 12S pump with a picture that would really help.
There has to be a bunch out there just have to get a picture by someone.
I'm not going to drill a hole until I'm 100 % sure on the location.
My boat sits on a raised shore station  when not in use on a lake where I live out of the water.
So every time I lower the boat it must sit in the water for a short while to allow the air to escape.

Could someone post a picture on the placement of a Air Relief Valve on a Dominator 12 S pump.
I started this question last year but have not drilled a hole to mount the valve as yet.
Want to do it right the first time.
Or measurements as well.

Many thanks

I need to add Hydraulic oil to the Place deverter pump reservoir .
What is the best way and what type oil to use?
The reservoir is tucked back on the inside transom so I can't see where to fill the oil.

Is there any chance of drilling into something where as to damage any internal parts.
That box is 6 inches out from the transom to the bowel.
Would 1/2 inch from the end of the box be a good place to drill ?
Just being careful. 

I have a Dominator 12 S pump with a droop snoop.
I keep getting an air lock when putting the boat in the water.
So I purchased a Air relief valve, but not sure where to install it.
I have a 94 Ultra jet .....there is a square plastic box on the transom that extends 6 inches out, then the round pump housing .
I only want to drill one hole.
Does anyone have experience doing this?

BTW, this is a great forum!!!!

Thanks, in advance
