What is Included
The 6803 Powerhead Gasket Kit is intended to provide the major gaskets and seals required during compatible powerhead disassembly and reassembly.
Exact contents should be compared with the product image and the parts required for your specific engine before beginning the rebuild.
What This Kit is Used For
A powerhead gasket kit is used when rebuilding or extensively servicing the engine powerhead. Removing cylinder heads, crankcases and other major engine components normally requires replacement of the disturbed gaskets and sealing components before the engine is reassembled.
Using a complete gasket kit helps keep the major sealing parts for the rebuild together rather than purchasing each gasket individually.
