140 Johnson question-trim unit

[wpvboat]

My trim unit is giving me problems AGAIN. I am thinking about taking it off. Does anyone know how hard it is to pull a 140 Johnson up by hand from inside the boat? I am 30 years old and pretty strong but I don't know. I keep the boat in the water so I need to pull it up when not in use. I think being in the saltwater all the time is my problem; the whole trim unit sits in the water and gets barnacles and other junk on it.
