I have a 1989 Force 150 model and serial number on bracket have been warn away. sticker on the head says 1501E9A. The T&T motor/pump sounds like its working when i push the buttons, however the motor does nothing. I have checked/filled fluid. When I remove the safety rod the motor will drop straight down. when i try to lift it back up there is resistance. I have a feeling that the Motor/pump is not pushing fluid all the way through the system. any advice/things to check would be great.
