Hi,<br /><br />i got a 1976 55 johnson, but one of the hydrolic arms is frozen. i took it off the engine, and took the pump off, but it wont budge, it wont slide up or down, it will, if u force it, spin, but only fi u froce it, i took it apart, and oil came out, but still it wont work, the seals are pretty old, so yeah, but any suggestions??<br /><br />thanks
