97 - 175 hp. Got home and when I raised the motor all the way up, I heard something roll down inside the bottom cowling. Took the cover off and found a loose bolt resting near the front latch. Bolt is approx. 1/2" long, not quite 3/8" in dia. and has #5 stamped on the head. Looks like the same one's used in the carb. drains, but i checked and they were all there. Is this bolt used anywhere else? Thought it might be one that got away from the repair guy but I would like to be sure.
