Cintocrunch brings up a good point. Since your Pilot is the front wheel drive model, you will be trying to pull your pontoon up a boat ramp with the front axles only. On a wet/slippery/steep ramp, this could be a real challenge with spinning front wheels.As long as you are staying within rated capability you will be fine. The chassis is more than up to the weight. Your issue will be the boat ramp.
