where on the website can I see specs: hp with weight - engines available, mounting specs, fuel efficiency, downspout available?

Asked by: mikebw
This information is not available on the website. For what engine is available you would need to contact a dealer as we do not sell direct: They will also have all the specs you need.

What's the power output out of the box?

Asked by: LRMcK
We tend to stay away from horsepower simply because organizations rule set differ, the method for horsepower testing in the field varies, and your final choice of exhaust systems will impact horsepower. Between all of these variables you can see a several horsepower difference. With that said to give you some general numbers are 6.5HP.
