yes 98795 is the short snout and aluminum and the reason I posted the link.. Many years ago I talked to maker of these engine couplers. The rubber and press in spline and its material has alot to do with the wot rpms along with steel holds and generates more heat. Aluminum disapates heat faster and better. And of course perfect alignment is needed with proper greasing every year min.

The longer snout is harder to align perfectly. Also the longer snout can generate more heat in higher hp apps.

Thanks for your time and info. I decided to call mercury racing and see if I could get some info from them. Scott there told me that all of their Bravio engines use steel couplers. I decided to go that way. I usually end up learning the hard way. Lol. Thanks again for your help and info on this.

I'm not sure how to interpret your post. I have never set one up. We had one installed last Fall. I have yet to run the boat with it. I've spun a coupler and ruined a few drives over the last four years so we're trying the DriveGuardian out this year. It's not fun when your boat doesn't shift into gear.https://cimg2.ibsrv.net/gimg/www.off...d0df68ef70.jpg

This is what it looks like. It replaces your coupler.

Ya I know what your talking about. I think it's a great idea, and will work awesome if set up right.
