I have done it a few times on my 1996 wards 18.5
first disconnect the battery and then depending on your model, my 96 had to have the hood and fender on the starter side removed. Then disconnect the electrical lines to the starter and then the 2 bolts holding the starter in place.
with a little bit of wiggling the starter will fall out.
Its really not as bad as you would think and it is definetly a do it yourself repair. Remember the top of the engine does not need to come off.
Good luck,
Paul
