    Somthing isnt right, RPM guage maybe, you should be spinning the 21 way into the rev limiter if you wanted. A 24 or 25 will def drop your rpm's significantly from the 21

    With your set up with any of those props even if your motor is as low as it can go you should still be able to rev it all the way. Before I did the flash the 19 P was perfect on my 75. Did you take out your air restrictor after the flash? It almost sounds like your running about the factory 75 numbers

    The 2003 115 was a stack 4, so not surprised it was gagging.

    Got it back for a while now.. Running great.. Sometimes the engine will start a bit difficult looks like it's gettong to much fuel or something but is starting..

    however a have a bayliner 16 feet boat.. And running with my old laser2 20 pitch off course to much rpm's 6000 haha

    so tested some others.. Running a trophy plus 25.. Holeshot is bad (with a the ventialtion holes closed) but can trim it very high and reachinh 5300 rpm by 49 mph.. Difficult to reach the magic 50 mph haha also running a ballistic 13.5x22 running at 5700 rpm by 47,5 mph..

    i was wondering a have smartcraft clocks (awesome things) telling me the fuel consumption is at wot 42lph how much is you're engine using at wot?

    Asked simon motorsport to reflash it to 115 horsepower but looks like it's the consumption of a 125 hahaha not a problem but would expect the 50mph a bit easier then with 115..

    No much action here anymore i think..

    However scored a laser2 24 pitch(old model with squared holes) seems to have less slip then the new quicksilvers.. However
    don't think going to hit the 50mph maybe i have to play with the height of the engine..
