This is a brand new High Performance SPAL replacement fan assembly with aluminum shroud for the Yamaha Viking or Wolverine. It replaces Yamaha O.E. number 1XD-E2405-00-00. This kit pulls 250cfm more than the stock fan, which is quite a bit and may be all you need to keep your machine cool on those hot days. The fan is water and dust proof with 6,000hr. brush life and a 3 year warranty. The aluminum shroud bolts right on to existing mounts using original hardware.This fan has higher amp draw because of the increased performance. The fan plugs right into your existing wiring and there is no cutting or splicing needed. This is a 10" SPAL electric fan and pulls 800cfm at 9 amps. We waterjet these shrouds out of 5052 aluminum and the corners are TIG welded.
