I have gone through 2 try's in 15 hours one set of lower gears were brand new, I am pushing big power for a TRS but the last RH went 2 seasons of extremes a use no failures .... So I am wondering now how many failures can these cases take? I seriously think there is a case issue helping mine die so fast now I don't have corrosion but had at least 2 explosions inside that I know of who knows how many before that.... Is there a point where it just won't hold anymore?

I am well state of all the issues with bigger power and TRS but should last longer then 14 hours

Who's building them?

My buddy Scott he's been doing them for many years never had issues like we're having all the sudden

How many times has the thought of moving up to 3A's crossed your mind? From what I hear the transom cut out is larger on the SSM 3A's so that is not an issue. I think really the only big issue for us TRS guys is the trans tailstock (other than the cost of the drives and props)

Oh it's in the plans for future, but gonna be at least 2 seasons away, I had more power in old engines as far as TQ goes, I beat the drives never had issue, until n ow... I wonder if there is crack inside case allowing flex maybe? or just weak? or just bad gears, who knows some live some don't..

Your setup is like putting a 14-71 blower on a 2 bolt main 330 engine, and wondering why the crank snapped.

TRS +650hp+heavy hull+rough water+aggressive driver = broken drives. Lol

You`re in denial! 1" prop shaft, nuff said.

What is the weakest part of the drive? I can't remember anymore..

Hahah wtf was I thinking? Oh well guess I need more spares!!! I have no idea how the last ones went 2 seasons of abuse

Lower gears and on a right hand pushes against the carrier the left pushes into the case...
