by John from Bellevue, Washington on August 01, 2013
Used the gasket but... the exhaust hole is about 1/8 inch too large all the way around.. only covers about half of the exhaust flange all the way around...the four bolts that I received are too large and wont even fit in the holes in gasket.. the 3/4 inch pipe plug has no use at all since this is only for the fresh water cooling application...if you used this plug and this gasket you would burn up your exhaust.thanks john mcbride. if you can get the manufacture to correct this problem please advise and I will reorder the newer gaskets. or email me...

Full StarFull StarEmpty StarEmpty StarEmpty Starexhaust elbow from sierra exhaust manifold gasket set
by Jimmie from Hampden, Maine on July 14, 2014
Poor casting. The slots for the 2 bolts nearest the exhaust exit of the elbow were not cast big enough to get the box end of a wrench onto the bolt. Infact it was necessary to use the open end of the wrench at a very steep angle to get them tightened down. The seal took because the bolts at the back of the elbow were tightened last. This really needs to be addressed by the manufacture.

Q:
Will this fit a GM 5.7 350 marine engine?
A:
We can only match it up by cross referencing the OEM numbers it works with. Those are: Barr # 20-0082 and Marine Power # 0992-000.
Q:
Will it fit on a 327F 1968 chris craft marine?
A:
We do not have a manifold that will work for that engine unfortunately. You will need to contact Chris Craft.
Q:
What are the bolt hole dimensions?
A:
Sierra does not have bolt hole dimensions unfortunately. It is only cross referenced by OEM number. OEM number for this package is 20-0082-P.
