I have a 1999 225 Ficht that is in need of a overhaul.The reason is it swallowed a reed valve,retainer and screws on #5 piston. It damaged the top of the piston pretty bad but didnt hurt the cylinder wall.Also it damaged head.I have another head and I am going to buy a complete overhaul kit with pistons,rings,bearings and gaskets.My main concern is what are the little things I need to know about this and What is the major diffrence in this overhaul and a 4 stroke over haul other than no timing?I have full confidence I am capable of doing this succesfully,I am a ase master cert. tech and als a gm master cert. tech. Plaes let me know the in,s and outs of this overhaul. Thanks in advance for all your help!
