from arneson ... maybe 1100 hp is too much??

My thoughts as well 1100hp+ reduction in gearbox = too much torque for a #7M
Louie why did you not go with ASD8-6 setup these can handle much more HP and torque.

I can't speak to the personal issues he is having with Ric but I have known since the day I put 7M's on my boat that they were a much stronger alternative to XR's - but they are not an alternative to Six drives. It's pretty common knowledge in the Arneson world that if you have 1100 HP mills that you should be running ASD 8's - not 7m's.

Oh snap.... that really sucks i can so feel for you bro....

Here's the chart: http://new.arneson-industries.com/wp..._selection.jpg

Now, the #8 says 1200hp for max rating. I thought I saw where his motors where dyno'd to 1205hp or something like that.

Edit in: Post #38 in link below. This was in 2013 so not sure if motors have been changed or detuned or something.

I have run 8s on all my boats with zero issues, in the middle of a build with 2 x 2000lbs torque motors on 8s, over there recommended rating but not concerned at all.

So rik specd to small a drive for the power he is running, and they are breaking drives...wtf rik should man up and send him some #8 drives. Thats redonkulous...
