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 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 else’s 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 it’s posted at the end of someone else’s 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.

Velvet Drive 71C rebuild trouble

  • Velvet Drive 71C rebuild trouble

    Just completed a complete rebuild on my Velvet Drive 71C. Followed the rebuild instructions to the “tee”, at least I thought I did. Today when I went to test my transmission it was stuck in reverse. I cannot figure out why. Any ideas before I have to completely pull the transmission again? Please help.

    If your shift lever is moving but nothing is changing then you need to pull the trans. Since its stuck in reverse something is not allowing oil cut off to the reverse piston or installed without proper clearance and its binding. Did you do a full rebuild or just clutch packs?

        This morning before work I checked the cable linkage to the transmission. I actuated the throttle lever and it did not move the gear selector lever. Somewhere the cable has come loose. In my haste of trying it out yesterday evening in the last bit of daylight I did not check if the cable moved the lever. I could freely moving the lever before I attached the cable so I just assumed that everything was fine. My assumption is that the cable must have come loose at the throttle lever when there was slack in it when it was unhooked from the transmission. I will have to look after work today. I HOPE that is the only thing wrong and I do not have to pull the transmission again!

            I went home at lunch and checked the cable. Evidently when I checked it this morning it was disengaged. I engaged it and everything moved correctly. The transmission selector lever moves like it should. I started the motor briefly and the transmission is indeed still stuck in reverse. On the way back in I remembered something odd when I took the transmission apart. I was going to write something in this post about it. My transmission did not have a steel clutch plate between the reverse friction plate and the reverse clutch pressure plate like the manual showed. I couldn't remember what the steel clutch plate was called so I looked in the manual before I typed it. This time when I looked at the manual I noticed at the section about re-assembling the reverse clutch it gives a reference to a chart 3 pages over. So I looked at the chart. Only then did I read that the 1017-001 series DOES NOT use a steel reverse clutch plate. Only a friction plate and the pressure plate. Well Crap! There's your problem right there!! So it looks like I get to pull the transmission and take the steel clutch plate out tonight!! Son-ova!
