Air in the lines. Replaced the seals and it seemed good. Took it to the lake and not so much. Pretty sure I bled them good. Wasn't seeing any leakage before or now. Whats next?

if you still have air in the lines did nit get it all out of the system may need to be bled againn

I would bleed it again. Last one I installed took quite a bit to get all the air out. It doesn’t take hardly any air to foul one up.

Definitely continue bleeding system. Follow MFG bleeding procedures to a T. You know it's right when motor trimmed down, steering wheel centered, try and push motor manually left and right. You should have 1/4" or less of movement in either direction. If more than 1/4" continue bleeding system and checking.

take it to someone with a power purge it circulates fluid thru the system til all the air is gone.

We have a puge machine we can bleed your system.

Turn the steering wheel slowly, it froths the fluid and makes air entrapment.

take it to a shop that has the machine to do it... you won't be sorry.

I have the purge machine to bleed your steering system

let me know I can bleed it for you

They're a PITA to bleed and you have to get every bit of air out. That being said you can do it yourself or better with the help of a friend. Take your time and do it EXACTLY as seastar describes and all will be good. Took me awhile to get all the air out of mine....
