    SpeedWeek 2019

    Glenn, Donna, & John, Only three weeks away, I can’t wait, it should be fun. Mark Sholund
  2. Tom, I hope those can get it done against the new Stealth Series Roadrunner boats. It should be a great test for a lot of the new boats. Good Luck And Have A Blast, Mark Sholund

    Brian, How is the new 12 boat coming along? Any pictures yet? Just Curious If You Have Been Busy? Mark Sholund

    David, Don’t you think our engines have changed quite a bit the last 20years? I know we have found more power in our tuned pipes, fuel, and head button designs. Do you know how much horsepower, rpm, and torque your engines put out currently? It would be nice to know what changes make a difference? A few years ago I had a chance to have one of my 12-engines tested on a Dyno, and we found almost 1/4 more horsepower and 10 more ounce/inches of torque from just a head button change. I thought that was a lot of power with just a head button change? Thanks For Reading, Mark Sholund

    Thanks John it would be awesome to get that dyno back up and running. I know there is still a lot more performance to learn about in our little engines. Pipes and head buttons are my main interest. Mark Sholund

    John, How much would the bearings cost? It would be nice to get that Dyno back to work? Could you ask Marty or Norm what it would take to make this happen again? I would be willing to pay for whatever it needs to get it back in service. I think there is a lot of useful information that a good Dyno will provide us all. Thanks, Mark Sholund

    Prop Gauge

    Tom, Could you tell me what propellers you are having launching problems with? I think it is the diameter or pitch ratio that may be your problem? Would this be on a 21, 45, 67, 90, or on your twin? With quite a few of the new ABC Propellers I find a lot of people are running too much diameter in warmer weather conditions that have the same problem. Thanks For Reading, Mark Sholund

    Prop Gauge

    Tom, It all depends on what you want to measure and reference as important. If you look at Terry’s picture above in post #13 it looks like he is measuring Leading Edge Pitch. To some that is an important measurement to how fast your boat is going to go. With the Wood gauge you can measure this real easy. You are only going to go as fast as you can rotate your Leading Edge Pitch right? Have Fun Testing And Enjoy The Competition Next Week, Mark Sholund

    Prop Gauge

    Bob, Most likely the heavy blade is too long in length from the hub. I just put them on my lathe and even them up again. If you are referring to a newer ABC Propeller, I would not suggest bending on them with pliers, this will offset the rake angle differently on each blade and it can slow the propeller down a little bit in some cases. Then re-balance and recheck it. Digital calipers work great. Thanks For Reading, Mark Sholund

    Prop Gauge

    Fellas, I do close to 500 to 1000+ propellers a year for the last 18 years and I own three of Steve Wood's pitch gauges. Easy to use and quite accurate for most situations. The Frank Orlic gauge which I have two of them also, are Very Accurate especially with a digital readout. You need something if you really want great performance from your set ups. With casted propellers there is quite a difference between blades sometimes, the only way you can fix them is by measuring them accurately, both gauges can do that Very Well. You cannot go wrong with either gauge, Steve made his rather simple and Frank went for a Very Precision Product, but it takes more time to learn Frank's gauge to get the most out of it in my opinion. Measure and keep testing with either one. You need to know what you are running, and the only way to do that is buy a good measuring tool. Thanks For Reading, Mark Sholund 231-590-3023 Props-4-U

    New 20 Tunnel from Sniper Boats.

    Bill, The boat came out nice. I found another propeller for you. Let Me Know If You Need Another Bullet? Mark Sholund

    2117, 2119, 2217, 2219, 2317, & 2319 are the most popular. It will depend on your set up like: motor mods, pipe choice, nitro %, weight of the boat. The Eagles tend to like the smaller diameters with more pitch. Enjoy Testing, Mark Sholund

    Joseph, 2617-19-38% is a good place to start and then move up to: 2619, 2717. All are good for that motor and boat. You got a great deal on that motor. Thanks, Mark Sholund

    Ceramic Head Buttons?

    Bob, We are working on a ceramic coating system for head buttons, piston crowns, and pipe surfaces. I will be testing it at Blue Lake in February on a few new motors. Happy New Year, Mark Sholund
