michigan wheel....p/n 012050, OMC P/N 382764.
13.25X17 UN-CUPPED.
A 391199 OMC is the cupped version, old blade style (like you have only cupped).
OMC 176214 is the later style, cupped, 14X17, michigan p/n 011024.
Depending on where your RPM is, you may need to drop to a 13-3/4X15 cupped..michigan p/n, 011002.
If you want the best performance, I'd go with a Stiletto 21315 SS Prop.
