Rather than just drilling holes, you should look into snow eliminators or better boards for your sled. People seem to like them. They run about $150-$200 for the set.

your heat exchangers are on the bottom side of the running boards on the 500 they should melt off the snow.

towards the back of the running board where i don't stand, snow builds up because the heat exchangers don't run all the way back there. polarisrider1 i'm almost about 1/3 of the way there. what are you asking in these summer months for it?

I would be very careful drilling holes in the running boards with you heat exchanger right there. Like mn mxz said - snow eliminators!

This is what I did to my Edge RMK running boards. All you need to do is drill out the dimple from the back side with a step drill to 1/2" diameter. You then need to make a compression tool to the size you want. I used 1" diameter roundstock, drilled a .500" hole in center, machined in a .875 x 45 degree chamfer. Use a 1/2" hardend bolt and nut, the bolt has to have the same angle as what you chamfered on the compression tool. Put the bolt in the drilled holes from the underside, place the compression tool with the chamfer down on the top side of the board. Put on a washer and the nut, tighten down. I used a torque wrench set at 35 pounds so every hole comes out the same. Oil the threads and washer, I went through a couple of bolts and nuts before I put lube on them. This really helped getting snow of the boards. Not as good as the "better boards", but alot better than stock. This is easy once you get started.

indy 500. I hope you don't mind but I am going to do this to the switchback. If all goes well then the RMK gets it next. I already marked out the pattern.

anyone interested in buying one of these dies, contact me. We are making them and putting them into a kit form with instructions. I am doing 2 sleds this weekend. Currently making a die to do 3/4 holes.
