Great idea....

What you are missing is that XR gearsets made of titanium, inconnel, unobtanium etc, are like unicorns, atlantis, and girlfriends that actually earn money.

They dont exist.

You can cryo and rem polish but it is what it is.


It takes an unbelievable amount of money to make gear-sets or you'd see them ripped off a lot more.

i agree they dont exist but wonder why imco and others dont check it out. maybe its stupid money but ill be damned if i put a scx lower on my boat. i would really like for someone to tell me the actual cost. i also believe you are probably right that someone would have already done it by now if it was cost effective. i work in the aviation industry and know what things have been done in the past to solve problems. the stock bravo gears are sh-t and just wondering with all the technology if someone could come up with something better! btw i did hear some rumors from boost power, but not counting on it.
i have done some research on the net (which is usually BS) about some companys that can copy gears in different metals and will follow up on it. but im not having a good gut feeling on it. we shall see. thx

smitty on here is working on stronger XR gears and hopes to have them out by the end of june at the earliest. I hope so because my Imco Sc's could use stronger upper and lower gears, or its Arneson or SCX for me also.

i cant wait to hear more about this

This is my favorite quote that shows up in all "bravo" threads.

...if you bought a corvette, would you baby it?
...if you bought a ferrari, would you baby it?


Every time I get in my boat I slap the sticks forward and hope for the best. The last time out in 3 footers I never overrevved the engines once, not even a blip in RPM and I still broke a tooth in flat water when I cam back in the intracoastal. There is more to it than babying the throttles, the gears just plain suck. (mine were even cryoed)

There is some great CNC technology that can be used to cut new gears, the problem is we need a good set of data to work from. I checked on using some of the latest surface scanning technology but it doesn't provide a smooth surface, it's stepped. So creating a working model is a lot of work. If someone can get me a set of good gears, I can get them scanned if someone wants to spend hours smoothing all the surfaces of each tooth. I will be glad to help in any way I can I have some money I would be willing to spend on this. I have a number of gear manufacturers in the Southeast Michigan area that might be able to do this reasonably. I've talked to some guys who know their metallurgy and they recommend billet S7 with a Nitride treatment. I am open to any ideas anyone has at this point

I've never chipped a tooth, but have broke a bunch of floors on stock bravos, so any improvement there would be great. I'm the same I drive my boat like its a race boat throttle hard but I pick my moments and keep a spare drive ready at all times just incase I need it

None of those will work well for a gear set. S7 tool steel would be a good place to start. I also don't believe it would be hard to make a set. With the latest CNC mill turns it would be easy the make, however getting a good working 3D model to program from is the hard part.

i know nothing about metallurgy i was just thinking something else could be used for the gears. no worries guys, just wondering. apperently someone is working on this, thx smitty. im excited about what could comes of this!

If anyone here has the ability to digitize a bravo gear set, I would be interested in speaking with you about machining a set.
