2006 Centurion Avalanche strut replacement

Recommended Posts

2006 Ski Centurion Avalanche w/BS 330. Last summer I hit a rock that did some serious damage to my prop and bent the shaft. I purchased a new shaft and coupler, prop and strut. Originally, the strut looked bent so I replaced it. Before I replaced the strut the prop shaft was off center of the rudder. I found this is common and a design that was used for a few years to make it easier to remove the shaft. I've also peeked my head under a few other Centurions similar to mine and the shaft is offset on a few. No vibrations or issues that would indicate a problem before the damage.
The new strut is straight, installed and now I'll need to drop the rudder before I can replace the shaft. This is where I hit pause. If I use the non offset strut I believe the shaft alignment will change. Has anyone done this before? Replaced an offset strut with a straight one. The offset of the original strut caused the boat to pull hard right under load and that's something I won't miss. My options are to buy another strut that is offset or take it to the shop for a full engine and driveline alignment. Thoughts?

I did a new shaft and bushings last year and found my shaft/gearbox off a little. Instead of dropping the rudder i chose to pull the v-drive gear box off, its a easy job a couple connectors and water lines, either 4 or 6 nuts hold it onto the transmission shaft and pulls off, mine had a seal leaking between the 2 so i needed to replace it anyhow. There are plenty of vids or write-ups explaining how to do the alignment, a shop is not going to be as critical on this as you will be (in my opinion), i got mine down to 2 thousands when i started it was 18thousands but didn't have to bad of a  viberation.

      Sad this forum is not as busy as it used to be since so many jumped to the Facebook groups .. the FB groups are not nearly as easy to search, and the threads do not get organized well ...
