    Thanks for your input Yamma-Fox. Just to be clear, when you said that when you spoke to "Tony at TMR he cited many examples of use in airboats used for wild rice harvesting where it held up great despite much more abusive use than aircraft." you are talking about the RK 400 clutch and not the TMR clutch, am I correct?

    Thanks for your reply Yamma-Fox. I had noticed that Tony's webpage is no longer up so I wondered if he was still in business. How many RK 400 clutches actually slipped from the Rotax 670 HP? I don't want to fix one issue, only to cause another problem with a slipping clutch, then I'm no further ahead and a with a lighter wallet. I asked Mohawk  about the reliability of the RK clutch and his sprague clutch, and he failed to reply to my questions.

    I know this is an old thread, but I'm also considering putting a clutch on my Rotax 670. How are the TMR400 clutches from Twisted Metal Racing holding out. Since this is an old thread, you guys using the TMR clutches have more hours on them. I also heard that Mohawk Aero has a sprague clutch for his Yamaha's and can fit the C Drive. I am worried that the RK 400 clutch doesn't have the reliability due to not being able to handle the horsepower of a Rotax 670. I appreciate any input you guys can share.

    Do you guys with Rotax 670 run clutch's in your gear box?
    I was wondering if you guys are running with the RK400C clutch in your C Drive reductions?  I have a 670, with a 3.0 ratio in the C Drive and  it's been years since I ran it due to health reasons but now I'm trying to finish the project that I started. I found that on start up, the 670 shakes pretty hard, swinging that 72 inch Warp drive prop but smoothens out by me adding primer and some throttle to get it to run/idle smoothly.
    My prop is 10 to 11lbs, which was recommended to me by Warp Drive. I think that shaking is awful hard on the motor, the drive assembly and even feel it in the whole airframe. 
    So aside from asking if you guys run clutch's, what gear ratio, what prop model, size and weight are you guys using?  Do you guys switch to a heavier rubber donut isolator?
     Do you guys suffer with the heavy vibration on start up and shut down like I do? 
    Thanks for any info you can share.
