My brother had a Nautique and he said his did something similar. He also uses a Malibu on a regular basis and says that it also does something similar (both are inboards though). He hasn't rode in the tige' yet to make a comparrison but his feedback is what made me think it might be normal. But from what some of the others are saying, they don't notice it in there tige's. We'll just see what the dealer has to say about it. Other than that and a few other minor issues, the boat overall is awesome.

Did they take out to check for a vibration, or they just verified that it was a normal characteristic while they were out joyriding in your boat?I don't want to go to work, take me wake surfing instead!

I gotta believe that Tige would not put a boat into production if it came standard with a vibration like that.I don't want to go to work, take me wake surfing instead!

I know that all gm small block engines have a natural harmonic at around those rpms. We get a very small amount of vibration too that comes and goes as we go above or below 1500-1700 rpms. I was told by a friend that works at a machine shop that every engine will do it, some a little worst or not as bad so that will change how noticeable it is. That engine speed in an auto is not typically maintained so the harmonic vibration isn't as much of an issue. Plus the engine in a vehicle isn't mounted nearly as rigidly so the motor mounts will absorb it more as well. There might be something making it worst than it should be, but I think it might be hard to get rid of all the vibration. Keep us informed what the techs think, I want to know for sure.

mtnsmith is correct, the small block gm motors are prone to give a little vibration between 1300 - 1700 rpms. I have an 03 22V that I purchased new from the dealer in 03 with the same vibration, this is our 4th season with the boat and it couldn't be better (no side affects from the vibration). Back then I verified the vibration with the technician and it is just the nature of the beast. I either stay above or below those rpm's while cruising. Hope this helps

I am the proud new owner of a new 07 - 22Ve and I am experiencing some what I feel to be excessive driveline vibration or shimmy at slow speeds mostly 1300 to 1400 rpm's. It is most noticeable as you are slowing down from a cruising speed and seem to level out at that rpm. It has done this for me since the first time I drove it off the trailer on delivery day. I am curious if this is just the nature of the beast or might there be a problem. I have asked my delivering dealer about this and they really didn't have a response other than maybe prop hit something. The prop looks perfect and the shaft does as well. As I stated, it has been this way since the first time I drove it. Any of you know if this is characteristic? This is my first V' drive boat and not sure if this is a normal condition. I have spoke to some other people that have had inboards and they seem to think that it might be normal.
Feedback appreciated, Thanks!
Ok so I had the same problem when i got mine. I have a 20V V w/v drive and I think I have the same trans. So I had the same issue. I would start the boat up and I would have a vibration. As I accelerated to about 1400-1500 rpm it would go away. Then if i slowed down to about 1500 rpm and under it would come back. I could feel it right under my feet. So I to thought something was wrong.
I traced the vibration to the back of the boat. Turns out my swim platform was vibrating at idle or just above it. When i accelerated over 1800 rpm the platform would have water forcing past it underneath that it would stabilize. At idle or slow speeds, it would be partially floating on the water and the brackets that hold it would rattle. Almost like the platform was semi loose.
So I went down to my local Kragen and got some clear silicone. Not adhesive silicone, the kind that you can peel off. I took my swim platform off and smeared the silicone into the bracket that hold the swim platform. I made sure to get any metal to metal touching parts covered good. Put it on and let it dry. No more vibration.
Hopefully this is you problem and nothing worse. Good luck!

The boat was actually checked this past Thursday for this. The service tech checked the shaft alignment, & mounts, water tested it, changed prop with another 24Ve, all while I was with him. I had the boat out this morning and the condition is the same. No change. He wants me to call him and let him know if any of this helped. I have noticed that the shimmy changes with boat laod. ie amount of ballast water weight and even turning it can make it change all though all of these items are still inconsistent. I really am starting to believe that something is out of balance, flexplate on the back of the engine, transmission internals, shafts, something. I guess this story will continue. More to come.............................
Thanks guys for all of your help and advice.
dogbert, I am interested in how the strut shaft can be adjusted with a tighter tollerance. Can you give details?I don't want to go to work, take me wake surfing instead!

I guess that would be possible also. The vibration isn't sharp its very soft and more like a quiver. The next time I am out I will run at that RPM and open the engine cover and just take a listen and look at the engine. Don't think that will be my issue by I am willing to look at anything.
