I will be changing all of the bellows on my 1987 Baja 240 sport with a 454 magnum Merc Alpha 1 drive. What bellows will I need to change all of them, and is Sierra a good brand to go with? West Marine carries both and says yes. I have thru hull exhaust. I recently purchased the boat, and not sure, what if anything has been done to the boat. Thanks,
Tom
