You will normally see water coming out of those two holes on the side of the lower unit. There will also be water in the exhaust stream and if it’s seeping out the shift linkage door, you just need a new gasket on access door. If you pull the lower unit to check the impeller, check to see if the impeller plate is sealed to the gearcase housing – if not, they will sometimes not pump properly. Also, with the lower unit removed check to see if the water tube up to the powerhead is clear (not obstructed) and see if water will flow up the tube thru the powerhead. Finally, there could be an obstruction in the cylinder head water passage preventing a full flow of water. These are some of the things I have found in the restoration of my QD-19 and QD-20 motors.
