I was removing an old temp sensor bracket from my 1986 225 evinrude when a small spring like object popped after i removed the cylder head bolt. The bolt wont catch to put back in..I have determ,ined that the sprink like object (now in the water somewhere)was a heli-coil thread repair coil...maybe the thread was stripped by the previous owner...DOES ANYONE KNOW THE SIZE OF MY CYLINER HEAD BOLTS??? I need to order a new helicoil repair kit asap...I believe it is part #26 from the evinrude parts diagram and may be part # 0322323....I cant find mention of the size or thread anywhere....thanks so much

Head bolt thread size is 5/16x18. Heli coil kits available at any reliable hardware or auto parts store.
