Yamaha Outboard Forum

This is the best Yamaha Outboard Forum on the internet, it's yours! If you own a Yamaha Outboard.   Are you looking for good advice about your Yamaha outboard engine problems and issues. All you need to know about your outboard engine issues and good advice from your fellow boaters.

From outboard engine and electrical and electronics systems to engine and alarm issues, tilt and trim issues, this is the place to find information.

Yamaha Outboard 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 systems.

My name is JOHN C PAYNE, and many of you may already have one of my books on marine electrical and electronics systems (The recently published Marine Electrical and Electronics Bible now in it’s 4th Edition) or perhaps one of the many other books on sailboats and yacht systems.

The Yamaha Outboard Technical Forum for Answers to Questions

I am not an armchair expert, but a qualified and practicing marine electrician and engineer and a marine surveyor. I do this for a living.  Let this website help you with the boat forum! Thousands of people input with answers to problems.

What is your outboard problem? If you know what the problem is then you are halfway towards finding  the right solution. Why not choose from one of my many books to help you fix your problems. Here are some hot topics for the boat-forum:

Battery Charging How to keep the power on and solve battery charging problems

Starting Issues - why wont it start?

Trim Tabs - and issues with same

This is just a fraction of the 3000 plus questions that were posted, and it is hoped that this NEW Yamaha Outboard forum and bulletin board does the same.

The Forum is also a great place to look for spare parts that are hard to find, share your problems and experience with others, ask questions, share stories and more about my books and related topics and a lot more. Create your own web page every time you submit an article and include great low resolution images as well. 

How to Post Questions to this Yamaha Outboard Forum

Forum Editors Forum Rules! Yes there are a few basics when posting!

1. DONT TYPE IN ALL CAPITALS as it will not be posted. Don't use any HTML code as it will be deleted

2. Don't use bad language or profanity as it will not be posted.

3. To post to the Outboard 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 sentences describing you problem and add an image if possible as it helps others. If you insert just a couple of words using SMS speak the system will reject it.

6. We receive dozens of posts a day and it is quite impossible to reply to more than just a few given this is a free site and I don't have enough time given I have a day job. 

7. It helps if you start the headline with your Yamaha outboard engine make/model number or boat make/model number. Save the problem description to the text, more detail means better answers.
