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.

  • Reducing total weight of a Ford 302/888 I/O?

    Is there any way of reducing the overall weight of a '78 Merc 5.0 w/888 drive? Any chance of getting 200-300 lbs off it? Aluminum manifold? What about exhaust system.....any way of reducing that weight? The 888 has a SS prop which I could replace with an aluminum one. Anything else that might help? My target weight is around 750-795 lbs overall. Is this even possible?

    Thanks for any input.

    That's the weight of a 3.0L 4cyl Mercruiser and drive. I don't think you're going to be able to shave that much weight off a V8...

      That's what I was afraid of. What's the weight of a 5.0 w/888 ? 1100 lbs?

        The 5.0L alone is 550ish. 1,100 is in the ballpark. You could go to Aluminum heads and intake to remove 150 lbs, but then you need to add in fresh water cooling to the engine which may or may not be available. If you boated in fresh water, then you could probably get away with just an aluminum intake because they are pretty cheep anyway.

          Yeah, I was looking at aluminum heads and saw that they'd cut about 50 lbs. Figured the intake was good for at least 100 but that's still a far cry from the target weight. Well guess I'll keep looking for a 3.0 .
          Thanks for both replies.
