1996 Force 75HP x 3 cylinder,#1 cylinder moderately scored,low compression, others good with good compression.<br />Question- Do I HAVE to either hone or bore ALL cylinders or can I just do the defective one? Probably only have to go .020" over max.<br />with new piston and ring. <br />Question- cooked due to overheat, problem remedied. What will happen if I run it this way. More serious damage or just a poor running motor?
