    SV and Wire Drive

    Guys I'm wondering if a wire drive would work in a SV setup.

    Some people have done it, but you will need to replace the stuffing tube.

      not sure if it pertains to the SV or not but i converted all my shafts to wire drive.
      its vry simple. just pull the cable out and push the wire in. Only on boats with a gradual bend. NO S bends
      i run with a .130/.150/.187 liner and let the wire float free inside the large stuffing tube.

        I have sold many for the SV. They work well. Very little bend in monos make these work well. If you can find another piece of teflon then slide it inside the existing. If not, remove the stuffing tube and put a smaller one in. The neat thing about wire is you can use a 1/8" KS brass for the wire. Just telscope it out from the strut inside the boat. The .078 is a good option for these if you plan to run more cells.

          Question, and this is not about ease of install, but which is more durable, I know with a flex shaft it compresses some ie: I can tell mines is going in my SV because I can turn the prop about 1/3 turn before the motor turns over, one the other hand our jolly with it's wire drive you' won't see that, also I've noticed on the jolly there is a bushing on the end of the stuffing box where the wire comes out next to the motor collet.

            No wind up on a wire. I still leave the 1/8" gap at the dog and strut. The wire will only push forward slightly. I would also recommend getting the trhust washers from OSE. They work great and you have to take it somewhere and I think the motor face is best.

            I have to say when you can use wire-- do it. Easy to maintain...lighter, less friction, smaller stuffing tube, Couplers plentiful for 5mm x .062. For bigger power the .078 is a nice size.

            Yes you can run them in the larger teflon already in the SV. There are riggers and hydros out there that only run a short stuffing tube thru the hull and open wire all the way from strut to coupler.

            THe one thing I do is keep the stuffing tube out of the strut as straight as I can until I have to make the bend. This keeps less pressure on the wire at the strut and generally only touches the inside bend. I also make sure my wires are coming out of the stuffing tube at the motor actually in the center of the tubing...not dragging against a wall of the stuffing tube.

              Hi Jeff!
              On a different boat,but related topic. Do you carry any struts with bearings that could fit my TLR system for a Black Jack 26? I need a bearing strut for my Black Jack 26 TLR system , the .150 cable, 5mm to .150 straight coupler and an Octura x 637 two blade sharpened and balanced propeller in bronze. Any info will be appreciated and its all for a BJ 26. Let me know so I can send you a secured Money Order for those items.
              Thanks with anticipation,
              Hans

                Yes but not sure if you are talking about ripping the stock out and replacing all with new hardware or not. I have stock struts made for .150 cable which would fit easily and then a rudder offset or centered would be needed. Steven has couplers for most of that as well.

                I was trying to find a good.inexpensive BJ hardware upgrade and may have it shortly. Looking at rudder set ups that can use the stock sterring linkage.

                That is the first thing I would do on a BJ...upgrade the hardware/strut. You can get the boat running much better and it can then be tuned to much more degree. Raising and lowering a strut without having to give it angle is probably the most necessary when running different props and dia.

                  I need your mail address to send you an MO for a strut with bearings,.150 flex cable joined and one 5mm to .150 tappered coupler. Also shipping & handling to Puerto Rico by priority mail.($)..thx.

                      In the pic, you will see that the jolly wire shafts have a brass bushing at the end near the motor collet enclosed in a piece of silicone tubing



                      Technical Details and Scope of Supply:

                      · Three- parts stuffing tube of stainless steel, hard- soldered and polished.
                      · Shaft of hardened-steel with (with gold plated ) thread -piece of M4.
                      · Optional bearing of Teflon, with thrust /sealing bearing Nylon, or stainless steel ball-bearing with thrust ball-bearing.
                      · At the front: bronze bearing with elastic support of silicone tubing.
                      · The fastening(with adhesive and laminated) is carried out with 3 pieces of vertically screwed M2 X 12 tap bolts.
                      · Precision -turned direct coupler of hard aluminum.

                        Jeez, sorry to get off topic but do you see much if any water pull through your driveshafts on your twin Jolly cat? I would suppose not specially with those drives made so nicely. Again sorry to get off topic

                          In general, wire drives do not suck water like a cable will.
