Hey Hondo, welcome to the other side. Ive got good news for you though. The WJ is a good pump, or atleast better than the other Jacuzzi offerings. I am not an expert and wont pretend to be, but I will tell you what I have learned in my short existence with this pump. There are two types of pumps, axial flow, and mixed flow. Yours is the latter. My understanding is that the speed you travel is dictated by the amount of water your pump will flow, vs. an axial flow pump which operates on thrust. From what I have heard, do not put an energizer kit on your pump. These are intended for use on the YJ pumps, to convert them to a mixed flow. You can also add a place diverter to help with planing, and to have rooster tail capability. Whatever you do, do not buy the Seloc manual on jet drives. It is a repair manual that covers many pumps and models of each, there are only about three sentences regarding this pump in the whole book, and a nifty diagram of the pump which can be found on the web(try the ADM website-there is a link on the home page of ***boat) The manual says something bout boats with the WJ being capable of speeds in excess of 100 mph, and that the publishers intent is to only cover stock applications-pure BS. Any way, try the place diverter website, they will have the parts to convert your pump to a rooster tail machine, for around $750 bucks I think. In other words, it is not a bad unit, its just not a Berkeley. But with some attention from a reputable builder(try Jack @ MPD, his # is on these forums a lot,and if you call him, he will tell you everything you want to know) and your pump will perform very well.
