[engineman44]

well my friend has a race hull gp760 wamiltons made for a 1100 motor he let me get this off so i could put trim on my super jet but its to big to fit on my pump housing would the whole pump and all fit on my ski or would it be too big and cause less power thanks (thinking its maybe off a 1200) just wondering what exactly its for so i can sell thanks part number 63m00 W1

63M is from a WaveRaider 1100 or WaveVenture 1100 and is from a 155mm pump.
BTW, that is a pump nozzle, not a pump shoe.
