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 threads or hijack existing threads. Old threads of a technical nature are like a library book, Please do not write in them.

2. Old threads should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • Winterizing a 1999 200 HP Optimax

    I've got a 1999 Optimax 200 HP I need to winterize. This is my first Optimax and I'm being told that I need to use outboard antifreeze. Also, I tried winterizing yesterday but could not get my engine to get up to operating temperature, ran it for about 1/2 an hour, I'm thinking thermostat but is there anything else I can check? Or is there something else I need to do to get the temp up high enough to open the t stats? Below are a few more questions about winterizing.
    1) After warming up the engine with the muffs I shut the engine down, attach the container with the antifreeze, open valve , start enine and wait until I see the antifreeze coming out of engine ports. Does that sound correct?
    2) As far as fogging, I've heard different things. Do I simply use fogging oil in each cylinder or just a few drop of oil into each cylinder. I haven't gotten the service manual for this engine yet so any advice is greatly appreciated.

    Ayuh,... Outboards are self-draining, 'n antifreeze is Not used, at All...
    Any Grease is Better,..... Than No Grease at All.......

      Thanks for responding Bond-o. This is my first winter with this engine, all of the other outboards I've previously owned never required antifreeze but when I purchased this engine the mechanic that installed the outboard told me that this particular model and year required the cooling system to be flushed with antifreeze due to the water jacket. Maybe he was just trying to drum up a little extra business but I wanna be sure before winter comes rolling in. Thanks again for the input.

        "engine oil" refers to 2 stroke oil.
