    Rehaul of a Mean Machine

    One might term this a “re-haul
    part rebuild
    and
    part overhaul

    The boat in this re-haul was originally built by Mike, CEO of Nautiboyz Racing.
    It was constructed as a learning platform for his son John.
    John has inherited skills that allowed him to learn quickly and not do extensive damage to this vessel.

    I came into possession through another member of this forum.
    I could not, would not let a boat with this heritage be scuttled
    or worse allowed to collect dust in a closet somewhere.

    So here is the rehaul of Mike/Johns’s Mean Machine.
    I deemed myself not worthy of using the “Nautiboyz Racing” name.
    I changed it more appropriately to “Naut A Clue Racing”
    (my vinyl diecuts need work but they are on par with my build skills.

    The chosen power plant will be a old Aveox 1421/1.5Y
    Juiced by 4s through a Fighter Cat modified 200A Suppo.
    A Octura X442 will be the first prop in testing.

    I received the boat with no hardware and being old and decrepit (me not the boat)
    with very little “toy moneys”
    I had to dredge up what I could and fabricate what I didn’t have.

    I also changed the color scheme to match my team racing colors - black and gold
    (- another loosing team I might add
    as I’m from the Pittsburgh area during the summer)

    The rudder and strut brackets were fabbed from aluminum angle
    and drilled and tapped to match the original transom mounting holes.

    I set the strut height from Mike original build specs
    It does allow for some tweaking both in angle and height.

    The rudder position was determined by the piece of AL angle I had on hand.
    (I live in a travel trailer and only have a jig saw and a drill for my machining tools)

    The stuffing tube was graciously given to me by “Henry Hound”,
    as was the link arm to the rudder – thanks Bill.

    I had the flex, drive shaft and the Teflon from an earlier purchase.
    (two years ago with my first boat an AQ Hammer)

    I burgled a servo from another boat and fabricated the mount again from a piece of AL angle.

    Mike’s motor mount was still in the hull and "if it ain’t broke...." came into play.

    A piece of scrap plywood will serve as a stuffing tube support
    all the other mounts were in the hull and will be used
    with the addition of velco battery straps.

    As it happens, the for mentioned “Henry Hound”
    lives at the same RV Resort as I and he also has a Mean Machine build in progress.
    He got his flood hull from “Encore Man” who also lives in this resort.

    Pictures show the progress thus far.
    I am hoping for a mid to high 30’s sport boat.
    All comments and suggestions will be much appreciated.

      Thanks Mike,

      I'lm given 'er a go.

      You built a very fine platform for me to work with.

      Got the stuffing tube hole enlarged so the tube is
      a straight shot until it gets under the hull.

      I put a drill bit in the motor coupler to set the
      stuffing tube/Teflon at the correct angle.

      I need to epoxy the tube and cover the hole.
      I'm thinking of a "pond" of JB weld.

      To hold or "dike" the pond I am going to super glue
      a thick rubber band around the opening
      and pour the JB inside.

      This should prevent the JB from speading too thin.

      I drilled 3/16" holes in the servo mount so when
      I glue it down, the JB comes up through the holes
      and form "rivet" looking hold downs.

      Am I way off base here or and just throwing beans at
      a wayward train?

          Maiden run went well

          GPS'd at a not so screaming 34 mph on 4s with a x442

          motor 119* F, ESC 105, bats 95

          Thats about all I'll get.

          She is sitting pretty when running and not wet at all.

          COG at 8.75"

          Hey it's a sport boat and it handles and turns great.

          On to the next built
          Nautiboys Triton 29

          Thanks for taking the time to read this.

            Glad things went well. Anytime you run a boat for the first time and not burn anything up, thats a good thing. Whats the KV on the motor and how long did you run it for????

            I never cared for the O-ring trick on the JB weld. To get clean lines I lay down some masking tape and apply the JB. When the epoxy tacks up after an hour or so, I pull it off. Makes for a cleaner look IMO.

              I agree the rubber banded JB looks
              well like a cobbler did it (pick me)

              I like your idea with the tape, will use it
              in the future. thanks
              Maybe I can clean it up some with your method.

              Run time about 2 min.

              Aveox 1412/1.5y is 2085 kv
              RPM 30858

              thanks for the reply

                  Thanks Jason.

                  This ones done except for some prop work,
                  I do like driving it!!
                  Mike, as I said, put down and excellent platform to build from.


                  on to another build of one of your fav-0-rites
                  also an ex-Nautiboyz build.
                  a Triton 29

                  Compliments form guys like you and Mike
                  mean alot to me, thanks again.

                    I hope Mike sees this!!
                    I took his most sage advise
                    and did the tape trick on the
                    JB weld job I botched
                    I think it looks much better.

                    Thanks again Mike, you rock!!

                        Looks much cleaner!!! O rings are for cooling Jackets.

                          I now agree Mike.
                          O-ring are for cooling cans

                          but
                          Not to leave well enough alone
                          (I think most of us suffer from this malady)

                          I was thinking the motor temp was due to inadequate flow through
                          the "Medusa of plumbing used to cool the ESC (see photo below)

                          Never a real fan of rudder pick ups
                          esp. one as thin as this
                          So
                          I fabbed a tube pick up.

                          I cut a length of brass tubing and then cut it long wise.

                          I flattened this and left a raised portion in the middle.

                          to this I soldered another piece of brass tubing cut at an angle.
                          Mounted this to the rear sponson.

                          Please remember I am not well to do and must do with
                          what I have on hand when I can.

                          I changed the prop to a 437/3 and went for a run.

                          Well speeds dropped to a dismal 30.4 MPH then
                          the ECS went into spasms and the boat quit.
                          Got the tugboat out for a rescue.

                          It had taken on about a cup of water, probably making the ESC
                          wet it's undies.

                          I blame too much H20 pressure on the rubber cooling jacket
                          (another "no so fond of" on my list. Do with whatcha got).

                          Gave the ECS a Corrosion X douching
                          (it recovered after drying out)
                          and a X445 prop is fitted.
                          Some sillycon sealing on the H20 jacket and

                          well see what tomorrow brings.
                          It still is a HOOT to drive!!
