This prop replaced my 14.5"X17
This has a steeper pitch of 19 and it seems that my engine runs quieter than it used to.
On the other hand, and this may be unique to the pitch change, I've been getting propeller aeration when trimming up to optimize plane and get the nose up a couple of inches. My top speed seems to be the same (since I can't get the nose up). I'll play around with a few things to see if I can fix the issue.

The quality of the prop seems great, but it was already priced higher than other props at a competitor of West Marine - and it requires a $50 hub kit that the others don't for less money. Next time I will buy a one-piece prop. West Marine should make it more clear for beginning boaters that a hub kit is required, I didn't know until I picked up my order from the store.

        Tried to purchase a spare prop 14 1/4 X 21 for 2009 Evinrude E-Tech. Dealer could not find a listing for that motor and therefore could not provide proper adapter. Great service by store personnel and refunded cost without question but could not use boat another day until a prop shop opened.

            Product was what the website recommended. Ordered online and picked up in store. Salesperson showed me additional parts that may be required. Glad to purchase even though it was not needed. Returned hub kit but prop was easy to replace and worked great.

            Service and delivery comments:

            Sales people were helpful. Only negative was returning hub kit and cashier seemed annoyed. Got job done and did her job very efficiently but just didn't seem like she was happy to be there otherwise great place to get my boat needs taken care of.
