Can you share your need to change ratio? I emailed you yesterday but not sure you got it. I was wanting to know if you had to go through a lot of prop testing?? Or spacer testing?? We are certainly not running the same exact setup, but I would like to hear what your experience was when you switched over. In my email, I explained that I was getting a bad porpoise at 75-80. IMCO told me to turn the props out and that helped a ton but now the porpoise comes on strong at 100. I had heard from Bruce (?) that has worked with several Cigs with SCX's and he said the drives needed to be run deeper. I'm thinking I may need to do the same. As a side note, I've never taken it all the way to 100+, Eddie was driving when we broke 100 but pulled out because of popoise.
Anyway, any feedback on your setup process would be appreciated. TC

So just got done reading all 20 pages of this thread and still don't really have a good solid answer as to how these drives are holding up!!!lol I am out of options on drives other than the SCX's. I am assuming after the research I have done on these drives and coming up with little to no answers, one can only assume they are staying together behind big power in heavy boats....reason I say that is you guys know as well as I do if they were coming apart, there would be sh*t all over the internet about them. Everyone comments when it goes bad, but not a lot of feedback after testing/using for 50-100hrs.
I have a 41' cat with a 12'6 beam with 850hp/800ftlbs tq that weights right at 13k lbs loaded and the boat paks very little air. Runs 98mph right now at 5200rpm and eats XR's as a snack!!!lol Not looking for anymore speed, I just want it half way dependable.
Before I pull this $35k trigger, can anybody give me some real life feedback that has a boat similar to mine and put time on it, not a 22' 3000lb single engine cat!!
Thanks,
Brad

Last winter we took out the 2" spacer to try. Boat still got on plane surprisingly easy. BUT could not maintain WP so motors kept heating up. If I turned I could get WP and cool off but got old quick. So we put spacer back in. As for ratio- when I was going thru XRs my 1.36s - the Cig seemed to like better. Why? No clue. Better speed and mid range. I have always turned Out w props and never tried In.
Best speed w XRs was 95 or 96. I am running close to 750 a side. I did lose a few top end numbers with SCXs. Thinking about blue printing this winter also.
Reliability!!! Did I say Reliable??? Totally - 100% satisfied- Should have done it 3 yrs earlier and I would have had them paid for with all the XR rebuilds I did$$$ Hours close to 150 easily.

I lost 8 mph but could not be happier. You can actually run your boat hard in real water!
