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 topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

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

3. Do not take over someone elseís topic (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 topic of your own.

4. If you have a question for the original poster (OP) and the topic 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 topic.

5. By starting your own topic, 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 topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic 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 topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic 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 topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

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

  • New guy with some questions here.

    Hello there boater people!

    Just getting back into boating after a long haitus and picked up a 14' morrocraft about a month ago.

    Looking around CL for a motor I found a 96 25hp Evenrude listed for $50. I figured that it would at least be a platform for a rebuild, but lo and behold, it runs!

    Both cylinders are right @ 90psi but it needs a pump and some other TLC which Ill do over the winter.

    My questions.

    Is there a for sale/trader page here?

    What is the name of the silver/blue paint they used on the 80's engines? I had a robins egg blue metallic 9.9 with a white cowl from that era and would like to duplicate that look. What brand paint to I use?

    Similar to this color.






    And lastly, is the cough in this video due to too rich an idle setting and if so how do I adjust?

    The idle is to lean that is why it coughs like that. I would also check compression with a different gauge as 90 is low. You also want to make sure the lower unit is in good condition. But otherwise really nice find.

      I looked at that video several times, and do not understand how you are goosing the throttle shaft like that without moving the spark advance. That alone will cause it to lean sneeze. That and the synchronization and slow speed needle adjustment.

        90 is supposed to be good for a pull start, IIRC. Atleast thats what the stickey in the "Secret" thread leads me to believe.

        Its a ***** to pull over with the plugs in.

        Im having a hard time starting it as I really have to rip on it, and this is hard while its on a stand, but also I think there is a fuel issue.

        I just cant determine if Im choking it too much or too little. Then theres the fuel bulb not getting as firm as I remember them to which has me puzzled.


        As to the advance it rotates until it contacts a pin on the left side, then when in gear that pin drops down to let the advance rotate fully.

        Atleast it looks right to me.



        Any good reasonable sources for used parts other than ebay?

          90 is to low a good healthy motor would be 120. There is no choke on that motor only a primer.

            ???

            Not trying to start a pissing match, but Im 290 and if there were anymore compression I wouldnt be able to pull it over with one hand.

            I have to pull it with one hand as without holding the stand with my foot and the motor with my left hand the stand would flip over.

            Im going to see if I can get someone to hold it and test it again so I can pull out all 5' of rope.

              You have the second plug out correct because there is no way that motor should pull that hard. With the second plug out and the compression tester in you are only pulling against one piston. Try taking the lower unit off and pulling it, something could be dragging. I have a merc right now that is a bear to pull and it's because it overheated and the pistons are scored and they are dragging.

                Yeah, both plugs out and coils grounded, just cant get it to spin very fast.

                Everything seems fine as far as I can tell. It seems the pull start pulley is only a little larger than the one on my old 9.9, which probably plays a part.

                I took the lower unit off today to replace the entire pump and it all seems in good order.

                Except for the bolt I broke.

                  for paint color when you get up to it, Diamond Blue used by Mercedes in the early to mid-80s is a spot on match, to my eye (some '80s Evinrudes). Dupli Color has it in one of its lines, I think, but some auto parts chains mix colors, and might be able to come up with it.

                    Thanks Oldboat, liiks like a good candidate.

                    Well I replaced the water pump and got it to pump water and now it seems easier to pull and the cough is miraculously gone.

                      Sounds good to me. I would dunk it in the lake or a barrel, water about half way up the leg. Test shifting at idle with some back pressure.
