I thought my water pump was faulty since I was getting very little water output from the pee hole at the top of the motor, but after testing it with the lower unit removed, it seemed fine. So I hooked up a hose with a tight fitting to the copper water tube that connects the water pump to the power head. It leaked quite a bit at the top where the tube enters a grommet. In my Clymer manual, I find absolutely nothing about how to access the area where the tube connects. Any ideas what the best way is to fix this and get a tight seal at the grommet area???
