Hey...

Thanks for writing

The threaded stud can be adjusted a bit. Dub also has 2 sizes available if needed.

The normal installation on the prop stud, is to thread it into the crankshaft all the way until it stops, then back it out about 2 turns. You do not want it to bottom out in the crankshaft.

To make it longer, you can back the stud out a bit more. Take the stud out, thread it back in a mimimum of 8 turns. This gives you about 3/16" of adjustment.
