1990 sp carb to 1995 carb

[hollywoodbadguy1]

hay everyone.
still pulling hair out over carb conversion.
cant seam to get anyone to tell me what the bn number should be everyone tells me to just get the sea doo carb not the after market. thank you i appricate all the help. but what is the part number and i just cant find anyone that can lead me to it.
forgive me i dident think it would be a difficult thing once i found the stock round carbs are shit." thanks to these forms" lol
is this the correct bn number for the 38 mm carbs i need to get it up and running?
BN44-40-43. i just want to make sure i have the correct ones for my 2 1990 sp pwc's
im sure you understand the frustration of paying for parts and they arrive the wrong ones.
thanks so much for your detailed response.
frankie ray your hollywoodbadguy. pulling out what little hair is left.

there are very few people here who would know... and You didn't like the answer you were given... so ?????


It's not that hard. The SBN's are basically all the same. If you buy an "Aftermarket" version... you will have to make everything work. If you buy a "SeaDoo" version... it will bolt up, and you will just have to re-jet it for your engine. (I think I gave you the specs before on that)

If you are all stock, I would suggest you pick a similiar ski SBN for SP a '95 maybe would be great. A fuel pump is integrated, not separate.
