This is a 10-piece Race Head Gaskets Bundle for 1991 to 2005 Mercury 2.5 Liter 2-stroke outboards.

 

This kit has been assembled from 3 of the world's top outboard head gasket manufacturers to provide a kit to tune your compression without having to change your heads. 

 

This kit is a must for 1) outboard drag racers (SODA, ODBA, DSRA, UMPBA) running a maximum compression rule class, 2) outboard tunnel boat racers (APBA, OPC, F1H20, AFPGP) with minimum squish rules, 3) other high-performance boats and tuners looking for optimal 2-stroke engine performance.

  • 2 x 0.75mm (0.0295" thickness) is suggested only for pistons below the deck height
  • 2 x 1.00mm (0.0393" thickness) is suggested for pistons at/under .002" over deck height
