EXCELLENT AFTERMARKET PART
by James from Hamptonville, North Carolina on September 27, 2011
This elbow is far superior to the "stock" units that are no longer available. It is solid cast for as twin-wall and the bolt mating end is stainless steel!

Q:
I just took down my 1975 198. I found that the port side elbow riser did not have a blocking plate and the starboard side does. Should both sides have the blocking plate?
A:
Yes both sides should have a blocking plate
