Question on a 2004 115 evinrude

[gshvwo]

I was using a lot of oil so I had a new pump installed. I continued to burn oil so a injection manifold was installed. Before these parts were installed I could achieve 5200 rpm's now my motor bogs down at 36-3800 rpms , what could the problem be ?

Was the new pump installed by an evinrude, or Johnson mechanic that knows how to adjust/check the flow rate? If so, I think I'd take it back?

Good luck.
