HP on sleds cant really be compared to hp on new 4 stroke jet skis. Jet skis have almost no moving parts in the driveline, and its an impeller in water. There is really nothing to break in the driveline unless you suck up rocks in your jet pump or hit bottom. Snowmobile drivelines are a cluster-%&$ comparatively. Lots of things to break, lots of moving parts and they have lots of traction. Plus the fact that jet skis keep getting bigger and bigger. I have a honda aquatrax turbo and my parents have a couple of seadoo sparks. The sparks to me are way more fun, half the weight, they accelerate faster and holeshot way harder.
I dont know how many guys on this forum have rode a legit 200+hp turbo sled. Its no joke, especially when you get that crunchy high traction snow. I trail ride at 11psi, so prob in the 225ish hp range. On days where the trail has good traction, it is downright dangerous. You need to have serious respect for the power and how fast it can get you in trouble. Cruising at 30-40 mph, you smash the throttle and it lifts the skis and youre pulling past the 100mph mark in seconds.
