Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone else’s thread (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new thread of your own.

4. If you have a question for the original poster (OP) and the thread is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old thread.

5. By starting your own thread, you will receive the maximum number of views by forum helpers that may not even notice your question when it’s posted at the end of someone else’s thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 1965 33 Evinrude Ski Twin

    I have a 33 Evinrude Ski Twin. I think it's a 1965. It has been in my familly for years, and is in very good condition. I'm pretty sure it's ready to run.
    I know a lot about 2 strokes and outboards in general. The problem is I can't find the ignition box for the motor. I am an electrician and have no problem building a new one, but what I can't figure out is how this motor charges the battery. There doesn't seem to be a 12V generator on this motor.
    The wiring harness has 2 black wires from the coils to kill the motor, a white wire that is for the saftey cut-out switch and a red wire for the power choke.
    The blue and yellow wires that on many other models would be the generator wires, have factory caps on them.
    Any one know how this motor charges the battery, or what important parts might be in the ignition box, that i might not know about?

    I am pretty sure that year of outboard requires a separate "generator". It doesn't have the charge coils built into the stator on this year. If it doesn't have the generator, I am sure you can find one on ebay, but expect to pay a good price for it, as they are expensive.

      most in those years did not come with a generator. As stated they can be converted, but parts can be expensive. If you flywheel is not set up for the gen belt you will need to change that first. Then get a generator and a belt. the belts are na so you will need to find a used one. Then inside the starter box will be the voltage regulator. It's better to just charge the battery for all the money it will cost you. I have run motors for days without needing to charge the battery. It is not needed once the motor is running. If you are not running lights and ect a well charged and maintained battery will more than get you through a weekend.

        if it has a generator it is a separate unit opposite the starter usually. belt driven.

        all that motor requires for a wiring harness is a starter solenoid, and battey cables, kill switch. i set mine up with just a push button starter switch, and a toggle switch to kill the motor.

          A voltage regulator for a generator will set you back about a hundred bucks.

            Get a solar trickle charger - they put out about 2 watts and work well. I have one on my pontoon for my '57 Lark electric start, with lights and fish finder. I put her in the water in April and take her out in October and don't have to put an external charge on the battery all summer.

              Thanks, that's what I was thinking of doing, but wasn't sure if it would be enough power to really be worth while. They have a solar trick charger on sale at Princess Auto right now i think. Maybe I'll go get it. My biggest problem is that i have an electric Minnkota trolling motor to run aswell. I can't believe they didn't come with a charging system.
              Thanks for the tips.

                tashasdaddy, thanks for the diagram. I have a starter solonoid already and some push buttons and swithches in my garage. I should have this wired up this afternoon. I might have to keep two batteries onboard for the electric trolling motor, cause I'm not going to all the trouble to get a generator hooked up. This motor has a pull start on top of it as well in case of dead battery. So I guess it should be ok.

                Thanks again

                  Hi there,
                  New to this forum, just bought a boat, motor & trailer (cheap) and the motor is a 1965 33 Evinrude Ski Twin. I've been fixing it up and am now replacing the head gasket. Just wondering if anyone knows the torque settings for this motor for the head bolts....thanks for any help!

                    Scott, first welcome to iboats.

                    This is an old thread about a different issue. Its better to start your own thread. I recommend that you entitle it, "1965 Evinrude 33hp Head Bolt Torque," or something like that. This allows people to understand right away, what engine you have and what the issue is.

                    By tacking your question on to an issue about something else, you just might be missing answers, because people who don't know anything about electrical systems, might not open the thread at all. At the same time, they might know the answer to your question and might have given the answer, if they knew what the question actually was.

                    Go ahead an open up your own thread - I'll bet you get an answer quickly.

                    Please don't PM me on advice issues - let's keep that in the forums, so that everyone can benefit. Please note that I do not email PDFs, etc. I have a bandwidth limited aircard for internet access. My avatar does not mean I have any offical link to iboats. I just like it!

                      Thanks, i realized that after (new to forums in general), but not sure how to remove it from this one....somehow I've ended up with it in about three places so I'm sorry!!!

                      Thanks so much for your help!

                        Welcome to iboats forums. The torque is 168-192 Inch Pounds. Please, in the future start a new thread when introducing a new topic.

                          Thank you SO much, I did start one but too late....learning forums and motors at the same time. I'll post my other question on my new thread. Thanks for your help.
