hello all! i dont post much because all the answers are already here, thank you. if someone can answer this question or direct me to some links that would be great! what rotax engines can be swapped in 93 and down ski-doo's. i realize that fans and liquids have to stay alike but can i swap lets say a 88 fan into a 77 440 everest? also any one have a swap story to share with us?
