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.

      Is there anything that can be done? Or I would have to replace the motor? Is there any way that I can get to the drive shaft and cut it? I would replace the Drive shaft than the whole motor, any advice, Iím dying to go fishing and Iím stock without an Impeller.

      Thank you

          when you took the pin out did you push the shaft in to free the shift rod?

          your driveshaft is not frozen otherwize it wouldnt drop a 1/2 inch.

            after I remove the pin (screw-in type pin) I was able to push down and up the shift rod with my hand, just to make sure it was loose, after the lower unit drop 1/2, I was pretty sure that something was holding the lower unit but I look all over to see if something was holding the lower unit from dropping, but I couldn't fine anything.
            Thanks

                  You must have missed a bolt, there should be 6 of them. 4 obvious ones that you can see, one under the plate, and then one more big one in the back of the lower unit, closest to the prop.

                  Also I have put some carpet down before and stood on the cavitation plate and bounced up and down until the L/U dropped, but that is only after I KNEW that all the bolts were out and the shift rod was completely disconnected.

                  I thought you had the pin type shift rod connection that you have to push towards the port side to release. If you say you have the screw type, then make sure you can move the shift rod back and forth, so you know it's free. DO NOT spin it or move it up and down yet, or you will adjust the height of it, and make more problems for yourself.

                    I can move the lower unit from left to right, it is very loose but it won't drop, I can also see 1 /4 inch of the thermostat housing, I can also move the shift rod back and forward and it feels very loose also, I was thinking on running the motor at 3500 rpm on ear muff, without any screws holding the lower unit. Just to see if the vibration will let it drop, but my battery is dead, so I will have to do that tomorrow. Do you know if running the motor without any screws holding the Lower unit can cause any damage to the motor? I know what ever is holding the lower unit it has to be something small, my guess is that rust got to the shaft and the rust itís whatís holding the lower unit but that is only a guess

                    Thank you

                      Running it can sometimes free up a stuck drive shaft (not at 3500!), but you're further along than that if it's dropping 1/2". You might try tilting it and see if the angle change gets something to unbind. You're real close, just keep trying.
