I have a merc.alpha 1 outdrive with an oildyne/singer trim pump.the unit will raise and lower O.K. but the trouble is, when I first start the pump it sounds like it is clicking off and on, after I raise it up and down a few times the pump will run smoothly. Also, when I lower the outdrive it will not tuck all the way in,it should lower at least another inch,the pump does not stop,but sounds like it has reached the full in position. If I disconnect the down lines from the trim cylynders I can then push the outdrive down to its full tucked position, but once I reconnect everything and run it up and down a few times it will not go all the way down again.Any Ideas?
