In high demand, all MPEM's, easy $200 a pop, seats are about $75 to $150. People break and damage sponsons all the time, $15 to $30 each. Pumps, $100 to $150. SS impellers $50. Driveshafts $50. Gauges $30 to $150. Carbs $20 to $50 each. Cases $50 to $100. Fuel Senders $55, Speed O sensors $60, Ride plates, Grates, Fuel Injectors, RAVES, Fuel Pumps, RV shafts/gear., VTS, exhaust pieces, waterboxes. There's a ton of stuff people could use at any point, I'd price it low on ebay and move some of it. You may be surprised. You could combine some stuff to make a good ski.
I wouldn't trash it, just store it and pull some out every now and then and try to sell it. On the FB forum people are looking for stuff all the time. I sold the old 96' GSX sponsons last week, which paid for my swap to the 98 XP sponsons I purchased a while back. Everything moves on there, one guy just sold everything from a 98' GSXL, he had a car full of boxes going to the post office within a few days.
I know it can be an addiction, but I wouldn't buy anymore skis...only way to stop the madness.
