i have a 1978 or 79 evinrude 85hp outboard serial number i dont know. does this motor have a fuel pump that sucks the fuel into the motor or does it pump air into the gas can which forces the gas to the motor? one metal gas can i have i put a gallon of gas and oil mixture in it to start my motor, about an half an hour after i shut the motor off it had oil around the gauge. the can is probably not sealed any more around the gauge since it is 30 years old, but would this mean its an air pump?

its about the size of a nail head, and at the bottom of my keel. my dad used fiberglass patch on it about 5 years ago, and it rubbed out after beaching it so many times. the boat has been sitting for about 2 years and i got it all done but that part. should i plug it with a bondo type stuff or should i re glass it? or both? and should i paint the hull too? thanks
