im putting a sx550 motor in a older js hull. the sx hull is messed up and i can get the 85 for really cheap and its perfect, but idk if everything will just drop in and i wanted to get your opinion if i should just find a 90 sx hull or just jump on the js and swap the parts. i would need to to swap motor, pump, and impeller i think but im not sure yet, i need to look. so any help would be awesome. thanks
