    Maybe you are right, the o rings are soft, so I did test(push) to se if it would give some, and it did. I will remove on and test again.

      What diam flex are you using, i bet the o rings dont squash any where near the diam of the flex.

        I don't understand why they're even there? I never use Orings or nylon washers and all my stuff works fine

          Miss Geico Perfectly balanced. Cut to length. Soldered end for better collet grip.
          Machined drive dog slot. .150 cable x 3/16 shaft. Complete unit with stainless drive dog, jam nut, prop nut and teflon liner. Has a 10-32 thread.

          I will test without any spacer/washer / rubber ... on the next run. It slided on nicely,and was just the diameter to close the gap in front of the strutt.

            Yep even a teflon washer dosnt do anything as the dog dosnt come into contact with the washer if the correct gap is left to suit the given wind up of a particular size flex. 2 piece shafts are different where it has a separate stub shaft that floats in the strut & the dog runs against the teflon washer, not comparing teflon to rubber here but pointing out the principal of why you need a gap.

              From my experience 3/16" Octura Lead Teflon bushings do not fit tight inside that strut when brass is removed. It looks like your lead teflon is spinning in the strut.

              When my buddies Geico wore out the brass I tried to put lead teflon in there and it was a no-go, too loose, the ID of strut was too large, all metric, 7mm or sumthin' ...

              I opted for a chinese strut I had lying around. The nose was just short of the brass tube but, the teflon made it in there with heat shrink, it doesn't leak.

              I'll take a pic soon.

                Are you using a teflon liner inside the stuffing tube? Have you tried a different grade of lubricant? I use bearing grease made for bicycles, myself. It has good lubricating properties, water resistant, and stays put.
                On a couple of my boats I have the teflon washer but not the leaks.

                  Try a small piece of water tubing at shaft in place of the nylon one. The tubing will give enough to not bind up ur shaft and help keep water out. How does it sound? Do you have a grinding noise or is it smooth sounding on bench.
                  I grease mine after every outing and it is almost dry also. Just thought it was part of the deal w the boat. When the grease runs out do you get a vibratin or grinding sound, if so something may be out of balance. Some older geicos came w the shaft wires the wrong way as another person said but I think you replaced it already anyway.
                  Last shot is there a crack in the tube I had that problem and water was pouring in from there. Also the bath tub will tell you real quick if it is anything else. Mine was leaking from the boot also and it would spray all over the lid also from hitting the shaft while spinning. Just because it's sprayed on lid does not mean it is coming in from the shaft. Try the tub just to rule out other parts.

                      Dæng. Moved again, to much Geico talk to be in the general forum maybe ? Hope some of you find you're way here, coz I have gotten many good tips from you now.

                      When I took out the flex last night I noticed a tiny play in the prop, ore not the prop, when i grabed the prop with my fingers to pull it out i noticed a tint play in the flex, so Ray, you may be on to something. It's just a tiny movement, but I can se it can be moved up/sideways a tiny bit. Will se if my kintec bushing is a better fit.

                      Boat guy: I have used kintec/ose flex from day one. Also did the bathtub, weight it down so I could see if it was leaking, dry inside after several hours.

                      Sidenote. Last night I could just go outside to drive my boat.

                        Today I installed a new flex, and went back to kintec bushing.

                        Do this gap look ok to you folks ?

                        Testing later today

                          Is this the new thread, not sure since it was moved.
                          Question do you leave the brass bushing in then the kintec. I thought you replaced the brass. In the pict it looks like it is in there still. I saw on another site , YouTube maybe of a guy pressing them in then reaming the hole for shaft w exact same size drill bit after its pressed in. It the fit that tight?
                          Let me know how it goes with install of kintec bushing. 3 hrs in the tub should have shown up if something else, so must be the shaft. I reduced the amount of water like I said w a small piece of tubing same as the width of the shaft. It has enough give and then flexes back as needed. Still leaks a little but much less when full of grease. I think the wire since it is twisted works like a pump w the grease. The screw pump is one of the oldest designs in the world. Looks a lot like our shafts. Just my 2 cents I'm pretty new to this electric boat stuff but have had to figure it out .

                            Same tread, pitty it was moved, probably since the Geico name was mentioned all the time :-) ore was it , hehe.

                            Out with the stock bushings, then in with the kintec one.

                            off to test now

                              Well I feel like dumba..

                              Today I sat looking at it before I threw into the pond, and started fiddeling with the cooling line, again , and whoa, found a hole in the line just at the water outlet.
                              Don't know why I have not seen/found it before. Did the needle test, pumping in water , but I quess when the boat is bounching around in the water the water is leaking.There has been a fine healthy water spray from the outlet when I pass by , but it has to been leaking good.

                              Still curious as to how the water form a spray pattern, and grease is at the flex exit inside the boat ( Not today though)

                              But anyhow, I want to give a preliminary thanks ( hope it will hold up now)
