Had a great time with Buckeye Boater and his wife.Was great having someone who knows the lake as will as BB. does.Stayed the night at Kelleys Island.Inspected the engine compartment to find 2 quarts of oil in the bilge. Spent the next hour looking for the leak to see if I could make the trip back home with no luck.Went to the store and bought 4 quarts of oil for the trip home.Engine ran fine oil pressure good made the trip home with no problems.When I got home I had 4 quarts of oil in the bilge.So I cleaned the bilge and hosed the motor down to find a hole the size of a large screwdriver on the top of the mechanical fuel pump and the top of the diaphragm which acted like a oil pump .
