While they share the similar blocks, they are different inside. The 15 E/J has roller bearing rods and is a larger bore. If you are considering swapping the complete powerhead, I think that will work. But because of different bore, the heads are different. Are you saying the E/J head doesn’t have the cowl brackets? I thought it did. But certainly could be wrong.
