Went to do my 1st oil change on my 149 and after draining the oil out I went to put the plug back in and all the threads in the oil pan are gone. Looks like someone has messed with it before cause the drain bolt is a stud with a nut welded to it. The threads on the plug are fine, just nothing on the pan left.
1st of all what size is the drain bolt as I don't have a correct gauge with me to tell and second, what do you think the best route to go to fix. Should I try the plug size tap and see if that works or go the next size bigger
