I've welded a bunch of these. Normally, I use my ironworker with a 1 inch punch to knock out some slugs from aluminum plate, and then I drill out the freeze plug, and weld the slug in place.   That was a wise decision to get a water strainer. It's much easier to un-clog one of these, than trying to unclog the cooling passages of your engine! The water strainer you have is the exact same type I am using in my boat. The only difference is that I am using the strainer screen from the model with the 3/4" inlet, as the mesh is a little more coarse than the screen used in the 1/2" model, less prone to clogging at the slightest thing. All parts from the 2 different models are interchangeable, such as the bowls and the screens.(I use the fine mesh strainer on my 3/4" filter for well water, to keep contaminants out of my pressure washer) Be sure to locate the strainer where it's easily accessible and visible, and be sure to check it from time to time. You'll be surprised at how much trash can accumulate in one.One other thing I would suggest would be a 2" diameter outboard motor water pressure gauge. You put a T fitting on the feed line from your pump to your engine (put it between the filter and the engine, not between the filter and the pump) Run the pitot tube from the T fitting to the gauge.   Set up in this manner, if your strainer clogs, you see an instant drop in water pressure, and you can shut down before you run hot, and clean your strainer. I put one on my jetboat, and I found it to be such a useful item, I also installed one on my 50 Merc on my Triton johnboat.</blockquote>
