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.

  • Sears Ted Williams 7.5

    I just purchased a sears ted williams 7.5. i've read the threads and understand the risks with this motor, it does have the electronic ignition....however, this motor has good spark and looks close to new so I figure the $90 price was a calculated risk. And yes, I like to tinker......

    My question, can someone tell me the year? Numbers are:
    model: 217-58820
    ser#: 153627

    Mix is 32:1 correct? It said don't use unleaded gas but have no choice....is that a concern?

    Re: Sears Ted Williams 7.5

    UPDATE.......turned out this was $90 well invested(so far). Yesterday evening I pulled and cleaned the carb.....it was full of oil???? I'm guessing the gas evaporated and the oil was left behind??, the motor hadn't been run in over 4 years.... Anyways, cleaned the carb up good, changed lower unit oil and reassembled. Put the motor in a bucket and it started on 5 pulls and runs great. Good spray coming from the leg but will order and replace the impeller anyway. Starts on 1 pull now......I will test it on my inflatable this afternoon.........so far so good.......

      Re: Sears Ted Williams 7.5 not getting fuel?

      Hello, this is my first time here but I've picked up a lot of good info while reading different posts. I have a '73 Ted Williams 7.5 hp It was running fine but one day on the water, it just cut out at low speed. Took a while to get it running but when I did, it wouldn't run for long. Took the carb apart and found the pump/element was split. Ordered one, replaced it, even put it in at a 45 degree angle (which I learned was the proper way on this forum, thanks) replaced gasket also. It started right up, thought I had it, but it cut out again. Checked the gas line from aux. tank for holes, nothing. The thing purrs like a kitten using the on-board tank but not the aux. tank so I'm guessing it's not pumping enough to pull gas from that tank. Also, I noticed there was no needle seat in the carb, why does it run so good on the on-board tank without it? Any tips would help, thanks!
