Yea well the issue is this, to use the spare prop, I need the current
spacer, which is a stainless spacer, if I shorten the spacer, it will only work
on one prop, basically I need to get a new spacer. However, if it's a risk obviously I don't want to do it, I'll just have to have a shorter spacer made. we can actually see the cotter key hole just peaking out, so it's maybe a 1/16th of an inch that I need to get the cotter key in.
