ok who can tell me the part number on this prop? i was just given a brand new oj force legend 4 blade prop. 13x13 1 1/8 left rotation. i removed my cvp off my 99 sunsetter lxi when i heard people were having them come apart. i got an acme 515 and now was given this oj. i'm wondering the cup size and part number on this oj. i checked there website and only finding 12.5x13 sizes with different cup sizes..... anybody have any idea what it is? first time i've ever had a score like this, brand new in the box for free. any idea which would be better the 515 amce or this oj? thanks in advance steve

Couple Things.

OJ Legend is the original 3 blade that made them famous (80's I am guessing)

OJ 4 Force was a step above. Most everyone used them in the mid to late 90's. Very smooth

If I am not mistaken these 2 above props were, (or are if they are still making them) made out of a cast mold and then hand finished. Again my terminology may be a little off but that is the gist. The downside is there is some variance in every prop. So If I had a 13X13 4 force all dialed in on my perfect pass and I hit something. When I went to buy a new one, I would need to time my boat in again as they may be a little differen't.

Now the ACME's and the OJ XMP are CNC milled to exact precision. No variance from prop to prop, and very smooth because of it.

You can't compare the numbers on the 2. For example I have an OJ 4 force 13X13 that carries similiar speed and RPM range as my OJ XMP 13 X 11.5.

Its confusing but I hope that helps
