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.

  • Yamaha 2003 HPDI VMAX 175hp

    I am considering purchasing a repossessed fishing boat with a 2003 yamaha hpdi vmax 175 hp. I would appreciate any information about the reliability of this motor and the recommended maintance schedule. For example what should I do with this motor when I get it considering I do not have any maintence records. The boat is well maintained from apperarance and I assume this would be a boat with less than200 hours on the motor. Thanks Rog

      Welcome to iboats.
      Let me get this to the non repair outboard engine forum.

      "Life should NOT be a journey to the grave with the intention of arriving safely in an attractive and well preserved body, but rather to skid in sideways, chocolate in one hand, martini in the other, body thoroughly used up, totally worn out and screaming "WOO HOO what a ride!"

        you need to check compression and spark, lower unit for water. compression should be over 100PSI and within 10% of each other. the following is good for all motors no matter what size. http://forums.iboats.com/showthread.php?t=158086

          myself, I have found if the previous owner could not afford the payments they also could not afford the maint.
          maint on that engine can get pricey and if its not done the results are very costly.
          try to have it brokered by a yamaha dealer and have them carefully inspect it and it may qualify for a used engine warrenty from Yamaha.
          just the engine mounted fuel filters are about 200 dollars, then ya throw in oil system maint and O2 sensor maint and it can get pricey for the 200 hour service.
          the service schedule is published in the marine technical guide that is shipped to every dealership.
          no tech questions by PM, they wont get answered.
          you have to be trusted by the people that you lie to .
