Any known problems with mercruiser one piece riser manifolds? I had them replaced and both 4.3L engines have failed due to water ingestion in under 100 hours of use in saltwater.
Thanks Blk-n-Blu, I was aware of this bulletin. I can't get a straight answer from Merc but I have heard that the one piece riser manifolds were a problem and I was hoping I could get this confirmed one way or the other.
