Looks like that boat and motor, with fuel, would weigh in at about 2,500 pounds. I"m thinking that you would be good. Power poles, batteries, and gear in the boat would add some but 5000 pounds of lift should be sufficient. If you are using straps under the boat, I would check with someone at Nitro about the placement of the straps to support the weight properly so as not to warp the hull.
I don't use a lift, so I'm not fully knowledgable about the issues. Hopefully someout out there is already doing this.....
