Difference between the oj 945 and oj 950

[Holdmybeer]

I’m close to 10K and the 945 works well. Just needing a spare prop. Saw oh has come out with a v4 wake/surf I think it’s the 1919. Looks
To be 15x12.5

I haven't investigated the difference between V3 vs V4. Here is the list for what would fit our boats.
