    The copper tube in this motor is only about 6" long and runs from the pump to a grommet in the lower part of the housing. The rest of the water tube up to the powerhead is a cavity cast into the exhaust housing so drilling a hole in the copper tube wouldn’t have any bearing on cooling the upper part of the exhaust housing. It would have to be drilled in the cavity where previously indicated to help cool the upper casting.
