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.

  • Gas / Oil Mixture for a 1964-50 hp Sea King

    We just bought a 50 HP - 1964 Sea King. The previous owner could not remember the gas/oil mixture. In addition, several sites we've checked give conflicting mixture amounts.

    If someone happens to know (for certain) the mixture amount, that would be incredible helpful!!! Thank You!

    Here's some additional info:

    1. It's a 2 cylinder
    2. We believe this Montgomery Ward Sea King was made by Chrysler. (model number VWB-19092)

    Also, do older motor run better with higher octane gas or is regular ok?

    And should I consider purchasing any fuel additives (besides the oil) that would help performance or longevity? (and with 'performace' I mean -running smoothly- than really about -speed-).

    Thanks in advance!!!

    That is, indeed, a Chrysler made outboard.

    Best fuel mix is 1 pint of TC-W3 rated outboard oil and 6 gallons of 87 octane unleaded regular gas. There is no benefit to higher octane fuel. That is 48:1, what we usually call 50:1.

    SeaFoam is a good additive to help keep your engine clean, and Sta-Bil extends its useful life and reduces creation of varnish.

      To nitpick a 64/65 would be a West Bend Became Chrysler in 66.
      The same animal.They do caution in my aftermarket service manual when running 50:1 be carefull that idle mixture is adjusted so any error is toward rich and high speed jets are selected carefully.sea level to 2,500 .096, 2500-5,000 .088, 5,000-7,500.080, 7,500-10,000 .076.

        Based on that, it sounds like 40:1 would be a good idea. A little more smoke, and a lot more peace of mind, I'd think. I'd rather err on the side of too much oil than too little. Internal parts are going to be tough to find, so why risk them.

        Sure...go ahead and laugh at my old aluminum boat. It's paid for!

            Yup. West Bend. My bad, though I doubt that it matters much.
