Does anyone on here have a lot of experience with these engines. Mine runs fine but there is a small hole in the lower unit that I have no idea what its for and I cant find out what it is anywhere in the manual. It is on the right hand side right in front of the oil level screw and in front of the front lower unit nut and up about an inch. Its about an 1/8" hole and when I flush the engine a little bit of water is coming out of it and I never noticed it doing it before. My camera takes huge pictures and I have had bad luck at trying to make them smaller so I guess PM me your email and I will send it that way. Thanks in advance.
