    I’m trying to leave prop as is. This run was with temps At 86 degrees, I’m also a big guy at 250. Next time temps should drop a bit and will see if wifey (120lbs)wants to get on and hold it wot for a couple seconds...she’s scared lol.

    I also want to pull the supercharger and make sure slip is set right. But that might give me the itch to upgrade to the ET 68-140 so I’m trying to leave that alone for now.

    Interesting build. What are the plans if it does go boom? Full build?

    I have another motor I can put together. Hopefully it holds together, this way I can put another ski together with that motor.

    I am going to put the ski away for the next couple weeks. I am thinking the supercharger is slipping. I think it’s finally broken in since rebuild. Going to pull it and check. Just can’t find my supercharger tool kit so I gotta order another one. I never checked the slip to begin with because I got the charger from a trustee member on here. Going to try to set slip around 15lbs or so.

    One more thought, the ski has the 155 cam in it as-well. Low-mid the ski pulls like a train but I feel like I lose up top. I might also flirt with swapping the cam to a 255 stock cam I have laying around.
