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.

  • Help with damaged lower unit gear case (fin)

    I need some advice. I forgot to raise the outboard motor prior to hauling the boat out of the water. The result was a scraped bottom fin and a piece of metal scraped off just above the fin of the lower unit. (The angled part that runs to the fin) Should I be concerned? Is it okay like this? Will it affect performance? Can a patch of epoxy me made for it. It appears that the damage is only minor. About a quarter inch of metal was scraped off.

    As long as the lower unit's chamber doen't have a hole in it, it should be OK. Usually,1/4" off the bottom of the skeg is not enough to effect performance.If it does, a device called "SkeGard" can be bolted onto the existing skeg.You should also check the lower unit for water after your next outing,just in case it broke it's seal. Use new gaskets on the fill and vent screws after refilling the unit.

      Dont worry about it, youl never miss it. It wont affect a thing, except resale. You can have a welder lay a couple beads on it, and grind it back into shape for prob $20 if it bothers you.

        I just bought a rebuilt lower unit for my 85 Merc from the dealer, and they reshaped the skeg from the normal shape to a triangle shape, as the bottom couple of inches had been lopped off. The mechanic(Mercury Master Mechanic) said that the skeg actually has no part in performance, and is just designed to keep mild collisions from damaging the prop.(Such as what you did)I've known several people who have ground an inch or so off at the ramp, and never noticed the difference.

          I have a "skagard" on my 130 Yamaha, it is held on by two screws one of them is broken and the other is loose. I've never seen screws like these before. What are they called and where can I find them? Also, how do I contact the manufacter of "skagard?
