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!

Product was fine, severe shipping issues
by Mike from Lumberton, North Carolina on May 18, 2012
Product was fine. Logistics at iboats getting the product shipped in a timely manner needs work. It was not shipped for 24 hours after I ordered the product.

Parts were fine. Shipping issues
by Mike from Lumberton, North Carolina on May 14, 2012
I originally paid for 2 day UPS shipping on Thursday evening at 7:00 PM. The order didn't get picked up for shipment till Friday night after 6:00 PM I finally received the order on Wednesday at 6:45 PM. Why, did my order sit for an entire day before being shipped If I had requested and paid $19 plus dollars for shipping????? Thanks, Mike

Review for Sierra 18-8512 Exhaust Elbow Mounting Kit
by a Customer on May 28, 2009
Was this review helpful?
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


Q:
Does this come with the gaskets?
A:
No that gasket is sold separately.
