Any assistance greatly appreciated.
There was a problem with some rams where they were not made correctly and they can go ‘open circuit’, if this is the problem it’s rams off and back to Lancing (or did you get them else where
). To test this, both hoses off and put an air line in one side, if the ram is buggered, air will come out the other hole
With regard air in the system, if it was working fine to start with I think it means that you do not have a problem, but just to make sure lift the out drive by hand while running the pump in lift. Once it gets to the top of its travel, pump the outdrive down and repeat. This is best done on the trailer but you can do it in the water with a rope around the prop. If there is any air in the system this will get it out.
The reservoir level on the pumps is not that critical because there is really little flow in the system when compared to some applications so providing it is about half full it should be OK.
If you want to save money and fix the rams yourself let me know and I will tell you what you can do.
