After reading this thread... :eekdrop:Is there a safe Zone for 2004 XRs? I don't want to wreck the OP's thread, but all of the guru's are in the house ! Before I got my rig I was told XR was ok to 700 HP. Now my rig is set up good ( an inch below the bottom) and I am hearing that the drives are too high and will harmonicly delamintate so to speak. I have a 5 blade prop that has 11- 12 slip . Is there any solution to save my XRs?

Trade me those shiny 7# blowers for my blue 4#ers.:lolhit:

I'm here now.. I'm never going back !!!! Kinda like you and your drives :lolhit:

Okay after pages and pages I thought I should update everybody. First let me say thanks to everyone especially Rik and John(Bravo Shop) I would not hesitate to do business with either of these guys as they are both top shelf. After talking with a few guys of all the setups and few others I have decided to order the Imco SCX's. I feel they are a good value a huge upgrade and will round out my package nicely. I will come back here and update the thread as far as getting them on dialed in and I will check in through the summer.

Your welcome. Glad all of us could help, or at least keep our minds occupied during winter! :lolhit:

Your choice makes a lot of sense, and one that I keep in the back of my mind also. The SCX has proven strength in the upper and lower, at a decent price. You can use your existing props (till you get the itch to dial the boat in even more!) Good luck and excited for you.

Thanks for the updates! :drink:

Why the SCX over the BMAX? I may need to upgrade my bravo soon and considering both of these for myself.

I went back and forth myself as I feel they are both great products. For me looking at resale in the future and the public perception is that Imco is a bigger company and more well known. Also the older Bmax drives have a bad reputation and that may effect how people feel about buying a boat of my price range with them. Not to mention the package came a small savings over the Bmax.

6's would make it an easy sale! Lol sure you'll lose $50k but who's counting!

Congrats and keep us posted how the swap goes. Happy boating!

For what it's worth, I think a swap (whatever brand) is the best for resale. That's just my opinion but let's face it, a boat with big power is hard to sell. With a drive swap you can easily swap out your big power for some stock power and install some bravo's when it comes time to sell and your boat caters to a much bigger market/audience than if it has big power with exotic drivetrain.

By the way, did you check with Zul on the SCX. There was a boat out there in Long Island with an SCX on a 32 Activator I saw over at MRD a few years ago. They had an IMCO Extreme SC on the boat before making the swap with a JC Performance blower engine. I was told they drive was holding up well but they lost a few mph.

Yeah I have heard that some people have lost some mph but from what I have been told it die the bulkier lower. I am sticking with my lower for now. All out speed is not my ultimate goal an I can always run a pulley change if it becomes my goal. My motors are 540 tall decks with Dart heads and an 871 blower only running 3.5 pounds of boost so with all things considered they are somewhat mild and have room for more power. I will let you guys know how the swap goes. I have Ocean Performance doing the all the rigging on the motor and drive swap and these guys do it every day so I feel very confident. The only question I have is I wonder if my X dimension will change at all. I am okay if it drops an inch or so as the early twin steps Cigs had a pretty aggressive X dimmension. Stay tuned.
