  • jb weld on trim fitting?

    I made my first really stupid repair mistake on my MC 120 outdrive. After 5-6 hours of trying to thread the trim hose into the connecting block, I gave up and just reefed it down cross-threaded, hoping it would hold. It didn't hold. Then I tried to re-tap it. Now it wobbles in the threads. I bought a new connecting block, but the trouble is, I can't get to the lock nut inside the transom (no way, no how) to replace the old one. My marine mechanic friend tells me there is no way it comes out with the motor still in.

    How silly is it to think I can slap some JB Weld or Marine Tex around the threads and fitting? I really don't want to pull the motor for this if a simple fix has a decent chance of holding.Click image for larger version

    Not a snow balls chance in .............. well, let's just say it won't work.

    The engines aren't that hard to get out. If you have a way to lift it, an hour at most and it's out.

          Looks like your old fitting is brass, you just might be able to braze a fitting into the stripped hole.

            Ever try to braze stainless steel fitting and line to a brass fitting? In tight quarters with oily parts?

              Forget the stainless and line, get a brass brake line fitting, 1/8 inch by the looks of it. Who pulls motors in an hour? Takes me that long to wiggle myself in there with some wrenches

                  Just kinda thinking out loud here... But can you drill it out larger, tap it, and use an adapter back down to original size?

                    Who takes an hour to pull the motor? 20-30 min tops!
                    When will people learn that impellers require regular
                    replacement and are not drive it till it pukes items?

                      Not everyone starts the timer after they get the boat in place, and the ladder set up, and the tools on the boat, trouble light hooked up, engine cover off and out of the way, seats out of the way, nor do they have air tools. And not all engines are that easy to get to.
                      That's what gets people into trouble with a shops quote. That quote has go cover the time needed to do the complete job.

                        amen...

                        thats why most shops quote an 8 hour flat rate for removal/install and testing for a motor pull

                        ive pulled motors that took 30 mins to unhook and pull, after 3 hours of removing, seats, bolsters, 200 lb engine hatches, etc...

                        to o.p. : search the forum for engine removal, you will find some interesting ways folks have pulled motors here, keep in mind safety first

                        and this is a great time to do some tlc on other areas/parts that are difficult or impossible to reach with the motor in place
