Hi. As far as I know…VP don’t offer the b series prop that most of these originally came with. The J series has replaced them, I’m sure. At an outrageous cost too. Not normally one to suggest straying from the OEM for parts, but I happen to know that the aftermarket alternative offered by Michigan marine, is known to be as good as it gets to the VP props…and not nearly as expensive. They offer a direct replacement for the b series. Hope that helps.
