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 elseís 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 itís posted at the end of someone elseís 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.

  • 1979 35 Evinrude lower unit removal????

    I need to remove the lower unit on my 1979 35 hp Evinrude I have removed the four bolts and top nut but something else is preventing the lower unit from coming off. The lower unit is one solid outer casing. I have ordered a manual but it has not arrived yet and I would like to replace the gear oil seals so I can get out on the water this weekend. Oil is leaking from the top of the lower unit and Water has contaminated the gear oil obviously since it was brown from where it is leaking up top and milky white when I drained the gear oil before attempting to remove the lower unit. So I hope it is just the seals. I plan on inspecting everything once i do get the lower unit off ie. berring, shaft, and water pump. Hope fully the seals are the only issue.

    Did you disconnect the shift rod located behind the intake screens?

        if the gearcase water inlets are cast in the housing you have the pre 1980 desighn. means on the stbd side of the ex housing about 6" up from the case parting line will be a small window held on with two screws, remove that window to access the shift disconnect bolt.
        if the screens are cast and there is no window you will have the second frankenstien cobbled Ebay motor I have seen.
        first one was wild.
        no tech questions by PM, they wont get answered.
        you have to be trusted by the people that you lie to .

            Thank you for the help. I do see the plate that you are talking about and the bolt to disconnect the shift rod.
