You have the lines correct.Your cylinders may be full of air on the down side.Those cylinders have a inner sleeve and the outer tube.The cavity between the too has to fill with oil all the way to the ram end and then push the piston in to lower the drive.First see if the drive will come down when you disconnect the UP line inside the boat at the pump.If that works then reconnect and raise the drive all the way up.Disconnect both of your down lines at the cylinders.They are the ones FARTHEST from the transom. Hit the DOWN switch to see that oil comes out both down lines.Now reconnect the down lines.Crack open the UP line inside the boat just enough to make the drive fall real slow.As the drive starts to slowly fall hold the switch in the DOWN position.When all the way down tighten the UP line at the pump.Run up all the way and hopefully back down.If this works run up and down a few times and it should bleed out any air as it passes through the reservoir.Also your wiring should be fine.That would just make your switch work backwards and we know it runs up correctly.

Picklenjim is right- I just looked at mine and yours again and they are right- when I looked at them the first time I thought they were backwards- my bust:eek: Thats what you get with free advise:party-smiley-004:

YEP ,,LINES ARE RIGHT !!!!!!!!!!!!!!!!!:ernaehrung004:

FYI Be sure you never let the reservoir run dry or you will get air in the lines.You can only run the trim cyls. halfway up or down when bleeding them before refilling the reservoir!

Jim you're the man! Air appears to be culprit. And I found out pretty quick how fast those reservoirs go empty. What ever I was doing actually aerated the oil to a point I had to stop and let the oil settle. Hopefully I'll get it finished tonight when I get home.

Thanks Scottie for checking those lines.

What a test of patience this was.

Glad to see things are starting to look up!! By the way which pumps did you end up using and do they have the plastic reservoirs or metal?

areyouliving 05-08-2009 03:51 PM

Later style pumps with plastic res. I actually only have one on so far. I left the other stock TRS one on until I had the problem solved. Didn't want to many varibles. This kinda sucks but when I bought the boat it hadn't been run in a year, and the pumps were either empty or super low on fluid. I might not have ever had any issues but air. I'm dumb!

79excalibur 05-18-2009 11:04 PM

I should have been on here last week I had the same problem. It gives me some humor thinking I am not the only one. Mine would go up but not down. I did all the bleeding process and everything you all stated I got a different pump and problem gone. I have not taken the old pump apart to rebuild yet but I think it is the check ball on the down side.
