Does anyone have experience removing the rubber boot from the 450/660 style gated shifters?

I prefer the more open style of the 700 where you can see the notches. Especially while plowing snow:

The 700 is a much more open assembly underneath. So maybe drill a small hole in the bottom of the assembly in my 450 to keep it from pooling water from rainfall? I do zero mud riding.

Just thought I'd see if anyone else has experience doing this.

If you look closely at your 450 shifter box, it should already have a hole in the bottom for drainage. There was a service bulletin released by Yamaha in 1999 to drill a small hole in bottom of the shifter box on the 600 for drainage as they were having issues with moisture/water entry building up and freezing the shifter solid.
As far as I know, all proceding models of Ultramatic from then on have a drainage hole already.

Thanks for confirming the hole, Dezz. I've never had my shift box off before.

So are you also saying I *should* be able to remove the rubber boot and keep it off without issue, like I'm thinking?
