The dealer we bought our spark from didn't carry any of the sea doo move trailers so we bought a Yacht Club trailer. We don't live on a lake so we pull the spark to our favorite lakes. Sometimes over an hour away. Most PWC's are almost double the weight of this spark and would work for this trailer but with the light spark there seems to be no suspension travel on the trailer NONE. We go over a small bumb and the Ski jumps up and down like crazy. Can't be good for it. Could we replace the leaves to lower duty ones? Fill the trailer with sand bags? I'm sure I'm not the only one with this issue.
