hi i have a 1965 merc 60 in great shape i picked up from the original owner with all the paper work from 1965 when he bought it. One question i cant find a tell tale hole anywhere on the motor . Does it come out the back on the big hole with some of the exhaust? I odlreder a new impeller kit and fuel pump rebuild kit waiting on them to come in just cant see a **** hole anywhere on the bottom of the cowling or any jose anywhere on the side i can find . I have looked all over so am i safe to say it comes out the exhaust port on the back?? Pic for attention all my other pics were to big of the motor to post
