I have a 2002 Yamaha 4 stroke F100 TLRA that has a broken tilt/trim rod. This is the stainless rod that goes into the cylinder on the tilt/trim assembly. Is it possible to weld this rod back together? The rod is broken toward the upper portion of it, not down toward the cylinder. Would the heat from the welding hurt the internal components of the cylinder? Also if this is not an option can the rod be replaced without having to replace the entire cylinder assembly?
