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.

  • Two of 4 cylinders hot - '96 88hp Evinrude

    I just got a 1996 88hp Evinrude in seemingly very good shape. Startes with a little effort, but no starter fluid. It seems to not get full power yet, it will get my 16' boat up to about 13 knots, not on plane.So the first question. After I had run her for about 1/2 hour I noticed the port cylinders were smoking a little. They were definately hotter than the other two, a drip of water boiled off. When I came off power and headed back, they seemed to cool to the same as the other two. Just hot to the touch, not burning.I just started her this morning and the port two got hot much faster than the starbord.The pisser is giving a steady stream.Could this just be a water pump going bad?Thanks!Rich

    Since one side is geting hotter than the other, it's not likely that it's just a water pump. Just the same, water pump and thermostats might take care of it......Wouldn't hurt you either to pull the heads and change the block deflectors.

        and ya may want to test your alarm, water boils at 212*F and I think the overheat triggers something like 190*F on that motor. in anycase the OMC alarm systems were not very reliable and need to be tested. cometo think of it I reccomend any make being tested periodically. but the t-stats need replacing just as the water pump does occasionaly. the key is to fix them BEFORE they break. the price of the T-stat and pump is the same whether or not ya buy pistons and machine work. and it sounds like you may have some carb issues as well. time for a compression and spark test before going further.
        no tech questions by PM, they wont get answered.
