I'm willing to purchase used, but there aren't very many parts for sale for my ski. I would like to get some sponsons and the opas block off kit. Are those parts the same for my ski as for an RXP. If someone advertises sponsons or opas block off for an RXP will it fit my ski? Which years will fit my ski?

I would also like to get some more horsepower. What are the differences between seadoos 185 hp 4-tec and their 215 hp 4-tec? Is it just the addition of the intercooler? Would I have do something different to the supercharger, injectors, ecu, engine internals? Has anyone ever successfully added an intercooler to a 185 hp motor?
