Looking at the prop, ( your last pic ) it looks to be stainless steel. Stainless props are about three times more expensive than aluminum.
The advantage of stainless over aluminum is they wear less in abrasive conditions. ( like running close to bottom ). Aluminum props are preferred in areas where prop strikes are likely as the softer aluminum will bend the blades instead of destroying the shafts and gears in the lower unit.
Both types of props can be repaired ( correctly formed and balanced) by the Marina or a subcontractor.
Your choice on what material you want to purchase for the spare. Make you you purchase the correct pitch. ( pitch is the amount of forward motion in one full turn with NO slip )
