I have a problem on my 1990 Dusky 256FAC trim tabs. I just got the hydraulic motor running in both directionsand to both tabs. I had to refill the reserviour and even though the pump is running nothing is happening. I am guessing the pump needs priming. If so, how? What else could be the problem? From everything searched on these forums, all invaluable information, I haven't seen this particular topic. Thanks for any help.
