2400 prop

[camnbo]

I have a "new to me" 2400, no t-top, with an f250. Need a spare prop. What size do I need?

If you know what pitch is on there now and it is working good I would go with that pitch. Most manfactures stamp the pitch size on the hub of the prop. Some stamp the pitch somewhere on the barrel itself.
