Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

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

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

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

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

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

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

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

    Just Reverse? Forward works fine?

        easy sleazy-lust the 6 bolts and ur off to the races. The hard part is after you get the drive off, separated the upper and lower (also easy) got it all apart-easy, bought the gearset from ebay for an incredible low price of $279, but now put it together and set the preload on the ring/pinion gear cluster without that stupid tool is where it starts to get confusing. I would start with the old "take the lower shift cable off the motor bracket and try to manually shift with your have while a beer-swilling friend turns the prop" route before taking the outdrive out. If you are going to go after the lower gearset in your driveway, pack a lunch when you do cause it takes a little while.

          well, little update. I have the lower unit off, now according to the manual i need quite a few special tools to take out the gears. anyone done this with just a standard tool set? I may just end up taking the lower unit to the marina to have the reverse gear replaced. (assuming that's the problem)

          also, yes the forward works just fine. its just reverse

            yeeeah, I looked at it and figured that I could get to everything but the part in the assembly where you figure out the shim distance on the pinion gears. I looked and looked for specs as I have digital calipers so I could set it up if I knew what it was supposed to be, or even the exact length of that tool. If you find it let me know because I basically adjusted my linkage to hold fwd hard and its not slipping anymore but I know it will be back to haunt me. there is a guy selling the gearsets for 279 on ebay right now which is cheap.
