Yeah Im just bored talking smack.
Remember you gotta follow GTs procedure to setup the new Gate if you install one.
Id try the packing first like mentioned hold the body with a backup wrench tighten packing nut 1/4turn
So, Along with the aforementioned GATE valve, I have a ball valve, down stream from the gate valve, on a tee, that goes to a garden hose. The garden hose is about 12' long, give or take, with a nice, polished, garden/driveway sprayer on the end. I unhook that hose and use the city water to the boat through that tee.
Hmmm, valved @ city water, gated to supply water DIRECTLY to the wear ring and impeller, and ball valved to supply enough VOLUME to cool the engine.
I've never thought about the WD 40 deal, sound good to me

That's all I got...
