In my experience, when the solenoid goes out, the starter doesn't turn over. You may get "clicks" like a weak battery. I prefer having a marine starter and I had a difficult time finding one other than the boat shop for over $250. There are only 2 bolts holding the starter in and a few wires to remove. Take a photo so you know where they go. I think it took me 10 minutes max to remove the starter, Probably 5 minutes to re-install.

Having your starter repaired ensures proper fitment and you don't have to worry about shimming in the starter if it is a replacement. I have found repairs are much cheaper than a new starter. You may not have electric shops around and it may be difficult to have it repaired.
