i put a 750 pump into my x2 a wee wile ago so i thought id put up how i did it to help anyone else that wonts to . the big plus off the 750 pump is you dont have to reseal it every time you take the pump out and a huge range off props you can get off the shelf with out modding (750 and 800)
the bigest part off the job is fitting the new pump shoe into the hull . it is slightly longer than the 650 shoe area and you have to reshape the new one to fit into the 650 hull and trim it to match your scoop grate . the 750 pump just bolts in like the 650 so i masked up the fromt off the pump and bolted it in . then i used epoxy resin mixed with filler power so it was nice and thick and glued in the shoe and filled round the front off the pump onto the masking tape inside the top off the tunnel and shoe so i have a nice area for the pump to go up against . once the resin had gone off and was sandable i removed the pump and sanded the inside off the top off the tunnel to match the pump and smooth the shoe area and that so the water flows over it nice .
then i sorted out the scoop grate as it bolts onto the pump diffrent than a 750 grate . it uses 2 bolts tather than the one like the 650 so with the pump bolted in i bolted the scoop grate in useing the front bolts and cut a wee bit off alli flat bar and shaped it up to match the area off the pump that it was going to bolt to and the scoop grate . then we tiged it onto the back off the scoop grate and drill the holes for the bolts to go thro into the pump .
now that the pump and the scoop grate all bolted in the ride plate need a slight reshape at the front by the pump so i trimed that up with a grinder and bolted that one and then go test
