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.

  • Winterizing and grease question - Nissan 9.8

    I was just winterizing my outboard. I just had a few questions. (This is my first outboard motor)

    It's a brand-new Nissan 9.8 electric start.

    I just completed the 10 hour break in period, and then another hour on top of that. It's now getting cold, so I've started winterizing.

    I heard you shouldn't mix grease types. The grease on the motor seems to be whitish or perhaps yellowish. What type of grease do I put into the nipples?

    As I drained the oil, I noticed that the oil had some sparkly flakes in it...they almost looked purple. There are a lot of 'markers' on the motor bolts - is that just flakes from a coloured bold inside the engine?

    I cannot for the life of me find an oil filter. I'm assuming it doesn't have one?

    I drained the fuel filter and the carb drain screw. I used extra stabilizer in the gas before I shut it down for the year. Is that good enough for the fuel system winterizing?

    Do I spray 'fogging oil' directly into the two spark plug holes? How much?

    I think that's all the questions for now! Thanks for the help!

    Re: Winterizing and grease question - Nissan 9.8

    There's a good description of the "factory method" at

    If you even need to grease the zerks after 10 hours, use a #2 EP grease, and push the old grease out, then wipe it off, That way, you flush any contaminants out with the old grease.

    The 9.8 does not use a spin-on filter.

    If there are visible contaminants in the oil, it should definitely be changed. Since the motor does not have a filter, that is the only way old junk gets removed from the crankcase.

    I don't understand what you mean by "There are a lot of 'markers' on the motor bolts - is that just flakes from a coloured bold inside the engine?" Can you explain a little more?

    Fogging oil can be sprayed directly into the air intake while running on stabilized fuel. That way even the intake valves, etc, get coated. You can squirt some into the cylinders afterward if you want to.

    I usually drain the carb, disconnect the rubber lines both at the carb and at the inlet connector, blow them out, then reconnect them.

    Now is a good time to change the LU lube as well.
