Full StarFull StarFull StarFull StarFull StarParts 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

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...

Q:
Does this include TWO gaskets per kit (both sides of engine) or just one?
A:
This does not come in a pair. This comes with one single gasket. The part number for just the gasket is 18-2949.
