I just installed a rebuilt prop(OJ 3blade 13x13) on my prostar 190. The boat pulls fine, but there seems to be a slight vibration, compared to my stock 4 blade OJ 13x13. I bought the prop from a reputable rebuilder in th area, but it is not dynamically balanced. Not sure if I should look into dynamic balancing.

A prop balanced correctly using the static method is as good as a prop done using the dynamic method. Prop could still be bent as well. Send it in and I can take a look at it.

Definately if you're unsure, send it in to Eric, but it could just be the difference between an old prop vs. a newer CNC prop. Even though the orig prop on my 190 was in good shape, the difference was considerable when I went to a CNC machined prop, much smoother.
