I have just spent my first week running a procharger M-1 on my 7.4l MPI and the universals in my Bravo III appear to be complaining. Noise side to side and during up and down trim. Replaced the Gimbel bearing last year and I have a stern Jack with an extra universal (big heavy boat). Looking for stronger Universals now that I have near 500Hp on a Bravo III. Do stronger universals exist and where do I get some?

You could step up to the bigger ujoints that came on the XZ drive, but you would have to switch the pinion gear.. some mixing and matching could be done..

Hope this helps.
