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.

  • Lost cowling for 1978 4hp Johnson.

    4W78E I lost the cowling today on the way to the lake. I have a parts motor but it was missing the cowl when I bought it. There is a seller on EBAY that says the cowls from 1969 thru 1978 are interchangeable. If someone could please confirm that because I have found a couple that I want to go see. But they both appear to be early 70s cowls. Also I would assume an Evinrude cowl would fit? Thanks for any help given.

      They have different part numbers but I believe that is because of color and graphics.

          I believe that unlike the 6-horse engines, both the Johnson and Evinrude 4s share the same lower shroud, meaning that the hoods will interchange. Actually the 1968 3 horse as well as 1969 - 1978 4-horse hoods should fit.
          The above is true for North American motors.

            Thanks. I did check the part numbers for the lower pan and 78 had a different number. There is no high speed needle on the 78 so maybe that is the difference.

              I don't think there is a simple way to replace a cowling, unless you find the same year and model online. I would look for outboard boneyards if you have them around (old time shops or marinas) -- need to have the same latch mechanism, appropriate openings choke knob and carb needles and knobs.

                The latches and front and back hooks are the same from 1969 thru 1978. And the rubber seal is also the same. So the only difference I see is shape which could be a problem because I have external ignition coils and a different flywheel. There are no openings in the cowls themselves so no problem there. The ones I saw that were an exact match on Ebay would end up costing me over 100 dollars.I would rather try to find a complete motor then pay that much. I know a few places I can check. One is close and the other is 1 hour away.

                  I am pretty sure the earliest of the 4s used different lower cowlings for the Evinrudes vs. the Johnsons. The Johnsons had a different shape to the cowling and the lower pan/cowling was a different shape to fit them. I believe the Johnsons used the same shape all the way through their run, so if you stick with a Johnson cowling, you'll be fine. The difference toward the end of that run in the lower cowlings was they added bosses to mount the power pack when they went to a CD ignition.

                    Yes I will be looking for a Johnson cowl. When I do find one I need to find out why it wont stay on. It has come off once before, and I thought it was because I did not secure it well enough. There does not seem to be any adjustment on the latch, like on some of my other motors. And it was kind of a sloppy fit. If I pushed back on it the hook on the front would pop out of the slot. And it sometimes rattled while running.I have not had the cowl off for a couple months. When I found out that it had come off the latch was still locked. So I guess it came out on the front and it blew off.

                      worked on a neighbor's mid-70s 6 about a year ago, and detailed the hood (fun to work on). I know the hoods go for big bucks (too much, imo) on eBay -- bought one for a '90 4 deluxe a while back (not sure now what I paid). I like the idea of picking up a parts motor for just the hood (and whatever other parts turn out to be useful at some point). Always feel I get my money's worth that way.

                      If you get one that needs restoration, I found vinyl decals on eBay for the 6, and turned out very nice.

                        I've found a few loose cowlings over the years - usually due to the belly pan having been distorted at some point. Doesn't take much. Motors get tossed in pickup beds, car trunks, etc. Gas tanks get put wherever. Stuff gets pinched, bent, warped, etc.

                          The guy I bought from was the original owner and it was used a few times each year. When I first saw it the cover was off and running in a barrel. It looked almost new and then I saw the hood. It was chipped and scratched and missing a lot of paint. He used at his camp in the north so it traveled logging roads and bush trails every summer for 30 plus years.
