So I added a marine bilge blower to my 12' RMK last year. Cut a hole in the clutch and had the fan blowing right down on the primary. Around 900 miles of hard mountain riding, I had warranty work that needed to be done so it got removed and put back to stock. We ride hard and my buddies would blow belts every 250-300 miles. During the 900 miles I changed belts a few times but didn't blow a single belt.
This year I decided to try something a little different......evacuate rather than try to bring cold air in. I have 1 vent on my clutch panel and a headlight delete kit, the rest is stock. I added a 4" bilge blower right below my secondary blowing OUT my footwell. I ran it the last 3 days in Revy in very deep snow on a belt that was old. I can tell you 3 things...
1. My left footwell didn't have any snow in it all day. I would stop after carving hard or sidehilling for 15-20 minutes and it would be completely clean while my right footwell was 1/2 full.
2. My clutches were hot but not nuclear and I tried my best to kill the belt.
3. My left foot was warm
So, for this next trip to the great northland, I went ahead and added a blower in the same spot on the right footwell. The 4" blowers flow 240cfm each vs 120cfm for a 3". They say they draw around 4 amps each which is perfect since I removed my headlight which draws 9 amps (55x2/12v). I have a 12w LED helmet light that draws 1 amp so I am electrically neutral!
A few things I will share....I did wire the blowers to a fused circuit with a 7.5A fuse and on the trailer it is fine. Also, the screws that hold the motor in the housing are not lock-tighted so you have to pull the fan and glue those puppies in there or they will rattle out and get stuck between the fan and the housing. Finally, I had to trim the one side of the housing for the left footwell so I had enough clearance with the secondary.
Cost for the Blowers at West Marine is around $30 each. Made the headlight delete myself.
If anyone tries it and it blows up there ECU, it's not my fault. I wouldn't recommend making any changes to your sled
Good luck and be safe!
