General comment from the above pics. If you are running a collet at the engine (which appears to be the case) I would have a greater distance between the drive dog and the strut, as the flex shortens under power you are at risk of snapping your flex and losing everything out the back. The washer you have between the prop and propnut should be between drive dog and strut to prevent potential metal/metal contact.
Also, I prefer to have some propshaft behind the propnut.
