Mercury / Mariner power tilt trim unit. Fresh water use only. This was taken from a 2010 Mercury 60 hp four stroke with a bad powerhead. It has been flushed, seals checked, it has a new motor, new pump and reservoir, new manual bypass valve, has been filled with fresh hydraulic oil, purged and tested for proper operation. It works as it should. I can ship this to you if needed. Any questions, please let me know.
