      This subject motor came on a boat I purchased seven years ago.
      I threw it in the test barrel when I got it home, started right up,
      and seem to run good, BUT, it shook like a Floridian in MN
      come January.

      I know at the time I read that these low profile models were noted
      for the rubber motor mounts breaking, and by all accounts,
      that seemed to be the case.
      I also remember reading that replacing these mounts was a real “Pain”.

      The parts diagram shows four different rubber mount, the opposing
      rubber mounts port and starboard, being the same.

      Questions –
      1. Does one remove the big “clamshell” housing off of each side of the 
      motor to access the mounts?

      2. If “Yes” to above, can the transom mount stay in place, so the motor
      can be worked on, on a stand?

      3. What “Non OMC” solution have you come up with to replace these 
      mounts, making your own, etc?
      The rubber mounts appear available, but I’m not paying $120 to do so.
      I tried to sell it for $65 a few years ago, and couldn’t even get a “bite”, lol.
      I do have a “froze up”, low profile 1971, Johnson, 9.6 hp, but not sure
      if the mounts are the same yet.
      Any thoughts on repairing this motor welcomed, before I “wing it”!
      Thanks.

        Have you clarified which mouints are broken, the upper or the lower?  The lower is usually OK and readily available but it’s the upper mount, on the front of the block, which can be hard to find intact and uually expensive when you do.

        I’ve had a couple shaky 9.5’s where the problem was the bolts holding the lower mount onto the exhaust housing  had worked their way loose. Tightening them back up helped get rid of the shakes.  Hard to remember but I think I turned the motor upside down and reached them with a wrench. The upper mount is a different story as they like to separate. I have fixed one or two by using crazy glue on the pieces and clamping them overnight.  The rubber and the plate must be thouroughly degreased and clean before the glue will work though.  It’s usually the upper which goes and when it does, the motor will shake like a wet dog. And yeah, if you can work on an old Merc, you won’t have any trouble removing the side covers for access.

        A good upper is worth its weight in gold  and that’s why I have one squirrled away somewhere.  In fact, I hid it so good I don’t even know where it is!

        EDIT:  Seem to be getting random photos again while posting.  The thumbnail is correct.

          The covers come off but pay attention which bolt goes where. (different lengths). Some of them are hidden up front. I’m going to bet that it is the front one that came apart. It was suggested to me to use gorilla glue. I think I found one on e bay.

            1966 did not have vibration dampers on the sides of the powerhead.  Consequently, they did vibrate a LOT at idle.  Well actually, they did have sort of a vibration damper, which was pretty ineffective and broke often.

             

            The first thing you need to do is determine whether or not the rubber mounts are broken.  Grab hold of the flywheel (not running, duh) and see if the powerhead flops all over the place, especially fore and aft.  The vibration damper will limit fore and aft movement somewhat, but try to evaluate what you are seeing.   And evaluate the vibration damper.  There is a friction pad glued to it, and is what falls off.

             

            Yes, the motor has to come out of the clamshell to replace rubber mounts, but not the vibration damper.

             

            Finally, OMC came out with a kit to update the early 9.5’s to later models with vibration dampers.  It makes a BIG difference.  I converted several of them back in “The Day”. Not a simple job, the motor has to come out of the clamshell.

              Vibration dampers.  early #32 & 36 first photo, and later #76 (x2) second photo.

                Buccaneer, I think you have parts missing.  A viewof the front, downward in the area of the throttle/shift rod area may help.

                  Mumbles, thanks for the tips on Evinrude’s and Washing my clothes, lol.

                  Matthew and Frank, It was seven years ago since I’ve seen it run, and
                  I haven’t done any diagnosing since I drug it out today, but
                  from what I remember running it in the test barrel, the powerhead was twisting
                  and shaking, and perhaps some metal to metal knocking going on in the housing.

                  I’ll do some investigating tomorrow.  and take some more photos.

                  Thanks!

                    Yeah, that’s what they did.  Instead of the flywheel inertia carrying it through the next compression stroke, the whole powerhead would twist, and it would stall.

                        I found a video on YouTube and watched that this morning,
                        then set out to tear apart the housings on this Evinrude.
                        I may never get it back together again, but thanks to
                        Brandon’s Garage, and you guys, it’s “Apart”.
