    Default Learned something new today

    When I had my 18' Southwind, if I were to put my diverter all the way up, I felt the boat lift when in it all the way. When i put the roost down a bit, there was a point where I felt the boat go faster. The "sweet spot". The sweet spot was when the roost was about 5 foot tall.

    I have been having issues with my diverter on my deck. Earlier this season I noticed that I am only getting 1/2 way up. (insert joke here)

    When full up my roost is big. I was playing with it (insert another joke) a few trips ago and noticed how free the boat rides. I made a GPS pass yesterday with my diverter full up. (its stuck in manual adjust in a fixed position mode) It was real hard to get on plane, but once it was, she was feelin loose.

    With my full up, I have made the best GPS pass to date. 82.3 mph. I was shocked. I am use to full up roost being slower, not faster. Anyone wanna chime in on why?

    I have a droop, and a one deg up wedge. I am thinking of more up.

    Im no expert so im sure someone that is older and wiser can chime in here. But at some point you start pushin the ass into the water therfore the sweet spot is before this point and where your boat is getting the most lift. Past that point your just raisin the bow and stuffing the ass in the water. kinda like tail stalling on a surfboard. Your deck may just be more to lift so all up is your sweet spot or closer to it.

    That turd is plowin' regardless! you were able to get the bow out a small amount and you gained a couple mph, imagine what would happen if you could actually get it to take a set! lol Wonder if there are any pics around here of "Here comes Wifey"? I know that it runs harder that 98% of every jetboat out there anywhere, but what does it look like at speed?
    Congrats on the newfound speed Dan! and you didnt even have to spend any more money for it!

    Its just heavy dan, my 21 wouldnt run unless I had a 20ft. tail. But youve seen my bahner killing it with a 5ft roost. And its the exact same pump nozzle diverter and motor. Plus your so aerodynamic now.

    It always seemed "aired out" when the roost was maxed out and the tips of the sponsons were pointed to the horizon. Ok, the roost was impressive, but I got my best numbers yesterday with the Place at the 4th notch from down. It was the best balance from huge roost and airing it out, but plowing the ass end, to pointing the thrust at the right level and packing air to get the best speed.

    82....that's moving Dan. What R's and what impeller?

    It would be great to see some pictures or video to see where the water is breaking.

    I am running a alum "AA" with inducer.

    I normally spin 5450 to 5550 depending on air conditions.

    I know she is an azz dragger and always will be. I know she is heavy, Tommy told me this when I purchased her. He told me it's way heavy. Heavier than any other 21.
