      I recently picked up this 1971 9.6 h.p. Chrysler Outboard Motor, which came with a fairly nice boat trailer of which I was more interested in. Upon getting both the motor and the trailer home I started looking a bit more close at the motor. Because Chrysler went thru bankruptcy the company discontinued production of these outboards, I’m guessing, in the late 70’s or early 80’s? As such, my question is this: Is this motor worth tearing into and trying to get it to run again? It looks real clean, but it may be froze. I’m not sure inasmuch as I recently had back surgery and I cannot yet muster enough back strength to pull hard enough on the starter rope to get it to turn over. Either way, frozen or not, would, I be wasting my time trying to rebuild this motor? Can one of you more experienced “old timers” give me your opinion? Much appreciated.

        Any motor, in my opinion, is worth playing around with and especially if it is in as nice condition as you describe. If the motor is tight, it may be just from sitting and a good soaking of the pistons and cylinders with your favorite penetrating oil may be all it needs to free it up again. If it has points ignition, they will need cleaning as will the fuel system. A new impeller would be a good idea to.

        A Mercury dealer would be your first place to try for parts as they took over Chrysler. (Force)

          The 9.6 was Chrysler’s best-selling small motor of the late-sixties, early seventies. It also led a parallel existance as a Montomery Ward offering.

          They’re not very sexy, but are simply engineered and solidly built. Can’t say the same for the 3, 4, 5 cyl. motors — the ring lands have a habit of dysintegrating and that was never fixed — I suspect fuel-starvation.

          I was able to get seals (Sierra) as recent as 3 years ago — try Crowley marine. Replacement coils are expensive — a lot cheaper to convert them to OMC coils by swaping out the armatures.

            Thank you, all. I am cleaning off the work bench in preparation of tearing into this motor, Would hope to have it up and running in a couple of weeks. Will keep you informed.
