    Do the HO pump. Carl has a good deal.

    I picked up about 3mph switching over.

    Im my opinion the gains arent from the HO pump. I think they are from the Dynafly style impeller.

    When I first put this boat together I installed a prepped 15/25 Dynafly into the old style pump. I did this because I already new that later I would go to the HO setup. I did not want to buy the HO setup at first because I was still dropping cash on rideplates and tabs. It worked fine for me and I gained about 4.5 mph over the stock impeller.

    Later in the fall I got the new pump and installed it and saw nothing. No change in RPMS no change in speed. I used a 8 run test in both directions with both pumps to find my results. Could be that later when the new bearings wear in a bit it may speed up but I dont know for sure at this point.

    This is just my opinion from my results, has anyone else tried the Dynafly in the older style pump???
