Was working on getting everything ready for spring and hooked my boat up to the garden hose to crank it up. For reference I hooked it directly to the v-drive inlet. I noticed that when I turned the hose on (engine off) the water pump was making a whistling noise like air was being pushed out of the system. Once the air was pushed out, it looked like a little water was coming out of the engine side of the water pump. Once I started the boat it stopped leaked and looked completely fine. Is this normal? I'm assuming the pressure of my supply water was too much and forced water out of the weakest seal. It definitely looked like it was on the engine side though were the shaft pushes through and not on the impeller cover plate side.
