Technically, no a JE is not a performance pump. That said, if you do or have done some modifications, that pump will perform quite nicely in most boats. If you are going racing or want to go 95 MPH you will probably need a different pump. I have a JE in my boat and after some mods by HI-TECH Performance I picked up about 10 MPH. I went from 66 to 74+ MPH. I put on a set of headers also.
