    Has the temperature of the shift handle ever been checked with an infrared thermometer to verify it is running hot in this area? As we get older, our sensitivity to temperature changes. I’d hold off drilling anything until you’re certain it is too hot.

    If you do drill a hole, there’s two things to consider. First, you are tapping into the motors cooling water supply system so the hole should probably be kept as small as possible to prevent bleeding off too much water and causing the powerhead to run hot. A 1/16" hole would be a good starting point and should be large enough if the pump is in primo condition. You’re not trying to drown the area with water, but just spray it. Second, the angle of the hole comes into play. If it is drilled aimed at the shift linkage, the hot exhaust gases swirling around in there might blow the spray away and down the exhaust opening. You might want to aim it forwards of where you want the water to go. Something like leading a clay pigeon before you powder it.
