Lose 1 cylinder and burn the piston ,low hr motor . Install a new sleeve in that cylinder.
The rest are good . Plans on just add new rings to the other 5 piston .
What piston (brand) would you use in the rebuild . Go back with a stock Mercury piston or what after market piston would you use .
The motor is a 2004 225 EFI .....down draft intake engine .
Thx
