Used Detroit Diesel exhaust riser DP9685. Manufactured by Marine Manifold Corporation. Removed from a non running 8V71, this exhaust riser has cracks between all of the exiting shower holes. The balance of the riser appears to be in decent shape with no other visible cracks or damage. There are several dents and dings as noted in the photos. This item is being sold for parts or restoration and should not be considered usable in its present condition. Therefore it is being sold as-is and is not returnable for any reason. Local pick up is encouraged to save on shipping costs.
