So many queries and questions from frustrated Yanmar troubleshooting owners.  Many are looking to resolve Yanmar engine problems and problems can be numerous.  Engine troubleshooting can be involved and finding forums or a forum that is active is hard work and a Yanmar problem forum that actually helps.  Yanmar engine troubleshooting can be challenging, and that is from personal experience, but well worth the effort.

Yanmar Marine Diesel Engine Forum

So you want to post on the Yanmar Forum? So where do you start? There is a lot to know. I get asked regularly about what is the problem, and more importantly and how to fix a problem. I am a boat owner and that’s why I have published a dozen books to tell you all that you need to know about how to take care of your boats and the onboard systems

About Me

My name is JOHN PAYNE, and many of you may already have one of my books on marine electrical and electronics systems. The Marine Electrical and Electronics Bible is now in it’s 4th Edition, and it has a big chapter on marine diesel engine or perhaps one of the many other books on sailboats and yacht systems. I am a professional marine engineer and marine electrical engineer. I have spent many years in the merchant marine as a marine engineer. Also within the offshore oil industry commissioning many marine diesel engines. There is not much I haven't seen or experienced.

Forum Editors Forum Rules!

Yes there are a few basics when posting!

1. DON'T TYPE IN ALL CAPITALS or BOLD as it will not be posted. No need to shout! Please do not use any HTML code in your post as it will be deleted, and if you attempt to add a link to some other website it will also get rejected.

2. Please do not use bad language (except on your own boat with your own engine) or profanity as it will not be posted. Politeness cost nothing.

3. To post to the Yanmar Engine Forum please at least use a first name and location with your email address in the notification page, so you will get a message when someone leaves a comment.

4. You need to insert a couple of clear, concise sentences describing you problem and add an image if possible as it helps others. If you insert just a couple of words using text message SMS speak the system will reject it.

5. Don't Spam the site with multiple submissions, as none will get posted. The posts do not get posted instantly so be patient. I review all contributions so be patient.

6. It helps if you start the headline with your Yanmar engine make/model number. Save the problem description to the text, more detail means better answers.

7. Got a different engine such as a Volvo, or Nanni then please post it at the correct Forum page for your specific engine make.

Do you have Yanmar Penta engine problems? Share it on the Forum!
