hello all, i need some help, i have a 2000 searay with alpha 1 gen II drive, the system worked properly last year and now the motor runs and dropsthe drive 1/2 way but just stops and the pump sound changes. the drive will lift to the trailer position no problem. when the drive is lowered the pump is still running but will not go low enough to be in the normal running range, as in, if i wer to use the trim switch(not the trailer) the drive will not lift. the trailer psoition allows the drive to lift the rest of the way(operating properly) but down is a no go. again, the solenoids are working, the motor is running. the fluid is at the correct level. i am assuming the pump itself is shot, however, i have never heard of a pump working in only 1 direction and only partially. thoughts?
