      Looks like a direct replacement for a TB type distributor but you’ll also need the ignition module, coil and wiring harnesses etc.
      I see complete kits that offer everything and are a direct replacement ranging in price 400 is on the low end.

          Regarding the distributor I would get a Mallory marine unit that is all in one, I.e. the ignition module is built in, these come as a kit with coil and wires for a reasonable price. Trying to replace all the Mercruiser ignition will be costly.

            So this is all I would need, right?

              This looks to be the Sierra replacement for the TB 5. I cant find if it includes a module though, maybe have to call them.

              There’s also this one.

              FYI I have no personal experience with either of these units.

                After having seen nearly 40 posts regarding a slave solenoid, I had to look in at this thread.


                Originally posted by Nauti_Mike View Post

Being the solenoid is not correct either you should review all electrical to make sure you are ignition protected for safety reasons.
                Mike is correct..... that automotive ignition system will not only offer an incorrect advance curve, it will not be "ignition source protected"!
                It could also land you a citation!
                I tell you..... a previous owner can sure mess things up when they start doing their own service and repair work in order to save a dollar!



                I have circled a few areas that I would be concerned with:

                ..... what's with the 2 wires at the temperature gauge sender? Typically, the main harness joins these in parallel for a dual station boat.
                .... the fuel line connection at the steel line is an un-approved connection.
                .... I would question the fuel pressure gauge connection!
                .... I am curious as to why the fuel line is coming up and in to the carburetor from AFT of the engine!

                .... you also have the Morse 33C cables and the 33C-to-Merc adapters. Look closely at these adapters for any signs of age related cracking!

                By the way and in my opinion........ if you found the need to replaced the risers, you should also replace the Elbows.


                As for an ignition system, as said if you go back with the Merc EST (electronic spark timing), you will also need the OEM module and harness.
                There are other good options!


                I would bet that these two EST systems are the same and are just being marketed differently.

                  Yes this would work and be all that's needed. Either of the ones Dave have links to in post #36 would work as well.

                    I see an interesting notation in the ad.

                    "Vacuum advance is locked internally, and centrifugal advance is suited for marine usage."

                    and it goes on to say:

                    "........ AAA MARINE PARTS WHOLESALE & Pertronix."


                    For me, the question now becomes.... which triggering system does that one incorporate?
                    Is it Photo-eye, VR or the cheezy Pertronix Hall Effect?

                      Yes the vacuum advance being locked with the centrifugal advance struck me as odd. A retrofitted automotive distributor with mechanical advance maybe😳

                      I missed that. I would steer away then but there are other options.

                    Just saw another item in the pic Rick posted. The flame arrestor doesn't seem to be secured on. Perhaps John P (OP) just has it sitting on for the picture, but if there isn't a post in the carb and nut to hold it tight it would be another safety concern and inspection failure. John P - you certainly have some work ahead of you on this one. But the PROs here (not me) will help you make thing right. Reminds me of my first boat with an I/O.
