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.

  • Johnson Seahorse # Impeller

    Could someone please tell me how to install impeller in model JW 14? Motor has not been run for several years, I did get it started but the impeller is shot. Could someone talk me through it? Also, where does thethe water from the engine discharge from? Thanks!

    Re: Johnson Seahorse # Impeller

    Egglayer--The procedure is a bit long and complicated for this post, but basically your JW-14 (a 3 horse 1957 Johnson?) is reasonably simple to get to the impeller by detaching the 4 bolts holding the lower unit to the exhaust housing. The lower unit and driveshaft then slip clear. You really need a good manual from here on, because there is a proper process to remove the water pump housing, screws, gaskets, and impeller, while at the same time keeping track of the small key that keeps the impeller in line. Go to a boat/outboard store and find either a Clymer or Seloc manual for your year. The overall process is straight forward, even for a backyard mechanic like me. Finally, the water should discharge from six small holes midway up on the propeller side of the exhaust housing. Water on my 3 hp Evinrude sprays from those holes rather than streams. Fair sailing.
