This is a trailered, 1987 Johnson GT200 6 cyl. Last month, all ok. This week,pulled the boat out of the shed, I raised the engine fine. Went to lower it, and it will not lower unless I open the bleed screw.
The motor runs both ways, sounds like the pump is running when I hit low, but no action. When it is all the way down, the trim pistons are out, and do not go in when the engine butts against them.
Tried the following:
Checked the fluid, slightly low but not much. Filled and cycled the unit through 8 ups/downs. No good. See below this for procedure detail.
Tapped the unit in case it had a check ball that was not dropping.
Swapped the relays, even though I did not think it was that.
Battery is good. (Starts the engine fine.)
I did not have to lock the engine up when I took out the fill screw, no pressure there if that is a clue.
To fill: I raised unit. Removed fill plug and topped off. Plug back. Opened bleed screw and dropped. Repeated several times. Never had to add fluid after the small initial amount. Anything I am doing wrong for bleeding the unit? Any other suggestions?
Thank you, G
