guys i am trying to change impeller on 70 hp evinrude ,but bolts on lower leg are seized twisted one of already ,dont see no way to get lubricant on them anybody have any solutions for this.thanks inadvance.
 
you could put a little heat on them and break them loose but you might harm the paint around them unless you have a pencil torch and your careful.....
 
you could try holding a phillips on the top of the bolt and smacking it with a hammer a few times, works once in a while....
 
These are 3/8" diameter bolts --------------9/16" open end / combination wrench needed.---------Use plenty of heat and you may break them loose.---------Do not overlook the hidden bolt under the trim tab.
 
A Propane torch is the way to go....adjust it to it's highest setting and direct the tip of the flame cone to the area you want heated. ( The tip of the cone is the hottest part of the flame). Do not heat the bolts but heat the surrounding aluminum. The large aluminum parts will absorb a lot of heat so you must be patient. Do not force anything. When the aluminum is Totally hot, the bolts should loosen. You should not need any more force than can be provided by a normal open end wrench. If it doesn't move, you did not heat it enough or you were heating too far from the area surrounding the bolt. Heating these big pieces of aluminum will usually require at least 3 minutes or more and is best done in still ( no wind ) conditions. Success will depend on technique and whether the motor was used in fresh or salt water and whether the previous technician used anti seize or not. Good Luck!
