1997 Sea Doo 787/800 engine. Removed from a freshwater ridden XP in nice running shape upon trade in. Good running engine that will make you a good replacement unit. Will work with other models running the 787 engine such as the GSX, GTX, and SPX. Compression is  a even 130-135 on both cylinders. The only thing the engine does not include is the carbs and the exhaust. Everything else is there from the OEM starter to the Rave Valves. I don't strip my engines down to the bare block as some do. Once you get your engine the only thing you will have to add will be your carbs and exhaust and drop it in. I sale quite a few of these engines so buy with confidence. Currently parting out several recent XP trade in units so if your looking for parts please check out my other listings. Thanks!
