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.

  • pcm 4140 on a 17 ft sunliner

    I bought this boat to keep out at my lake house, and the upon recieving the boat I cleaned the carb, changed plugs and coil, changed the oil and cleaned all of the connections. Ran it a couple days and everything was fine, the temp was at 170-180. And oil press was fine. Then I was pulling a tube and the motor all of a sudden cut off. Just died down like I ran out of gas. I still had half a tank and the engine was getting gas. But the boat was now reading 220 degrees. So I let it cool down.to 150 and tried starting it and it wouldn't start it just backfired with a lot of white smoke. Checked my coolant tank it was bone dry. And in my gas filter had a little water. I emptied my gas tank. Now for the engine what procedures should I do to find the problem, also can I even buy parts such as gaskets for this motor.

          Hello Phil,

          I have the same set up on the same boat (mine is the inboard version). There are quite a few of those motors around, and you should have little problem finding most parts. The PCM 4140 the the marine version of the mighty max truck, and most part will fit. The marine related parts can be found at www.skidim.com, I was able to locate most I was looking for there.
          I have also relied heavily on the advice of members of Fish the Classic, a shamrock forum, since the shamrock 17 has the same engine.
          A problem common to most of those engine was the corrosion of the ex. manifold, especially near #4cyl. with time, the damage would extend to the cyl head. I replaced mine a while back.
          Good luck, I have just started working on my boat after several months, if you need anything drop me a line!
