    78.4

    well just an update, forgot my tach yesterday so I'm going out today to get the RPM but boat ran a 78.4 and 78.0 1200 grate stock ride plate. Short run too because my boat starts to buck. I will be shimming the tabs down some hope today is better I would like to do a superman for a nice run but it gets a little scary when the ass end kicks up this was with the new pump and the dyna fly. How ever the back of the hub to prop would not tighten up close to stater vein it was 7.74 mill away from stator vein section this was my prop from Impros. Go any closer prop locks up.

    Well, went out today not so great wind was a 15 to 20mph cross wind so testing was not the best first run went 78 at 7270 after that was 75.7 to 76.4 with boat coming in and out of the water. so rpm readings were up and down. I am guessing the rpm readings will be at least 7300 so I will need to re-pitch and the boat feels like the ass end is still kicking but water was rough so I will test again with diffrent prop and some more handling things
