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 else’s 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 it’s posted at the end of someone else’s 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.

  • lube throttle cable

    My first question here- I'm sure there will be more! I just bought a 1989 Penn Yan with a 4.3 liter Alpha 1 drive. The throttle is fairly difficult to move, and I'm wondering if the control cable could be binding slightly. Is there a way to lubricate it? If so, what should I use? Light oil? I read somewhere about lubing cables with dish soap? Another thing I want to check is the exhaust manifolds and elbows. This boat was used mostly in fresh water, but the previous owner told me that he used it occasionally in salt water. If I remove the elbows can I make an educated guess about the condition of the exhaust manifolds by looking down into the water passages? Thanks for any and all replies / suggestions. Steve

    Welcome aboard.

    Can't answer the exhaust question, but it is virtually impossible to lube control cables. Often cables become sticky and hard to move when the internal sheath wears at bends and the cable wire corrodes. Lubing the cable may improve operation, but only for a short time. Replacement is the best option.
    Please, no PM's (Private Messages) regarding boat/engine problems.
    That is what the forums are for.
    Only forum/moderator issues will be answered in PM's.

      I'd use marine grease to try lining the only bits you can lube.
      The throttle linkages at each end and at the remotes. There are mechanical linkages and moving parts here.
      Likely a new cable is required or will be soon.
