The guy at Mud Buddy I called today (Micah) said the correct prop for my used/new-to-me 2008 Mini 18 (on my heavy 16" aluminum jonboat) is an 11 x 10, 3/4" hex, part # P-05. I measured the one that's on it today and it's 9-1/2" across. Hopefully the 11 x 10 will give a little more power? Anyway, before I order it I want to remove the old one to make SURE it's a 3/4" hex and not a screw on. So what do I need to remove, just the nut on the end of the shaft, or the big fitting in front of it too? (Isn't that a bearing in there?) The "Prop Removal" page on the Mud Buddy site is confusing--the photos don't seem to match the text, which itself isn't that clear, and one shows a wrench on that big rear fitting.

If mine's in fact a hex, I think all I need to do is remove the little end nut and then tap the prop straight off the hex shaft. To keep the prop from turning when I bear down on that end nut with a wrench, I think I can use a piece of flat bar with a hole drilled in it and slip the end of the bolt through the hole and wedge the bar between the blades to keep them from turning as I crank the wrench.

Am I correct on this procedure? Does the 11 x 10 seem the correct prop? Any ideas as to why there's a 9.5" prop on it?

Here's my current 9.5" prop:

Should be able to just take the nut off! My 23 looks just like that and I just backed the nut off while holding the prop or you may have to put something under the prop to back it from moving.
