Couldn't you ask a simple question, like "What's your favorite engine oil?".

As Thrall quotes in his posts: "I understand why some people may not want to do this the way I have recommended but I can't understand the death grip some people have on a toilet plunger with a hose fitting." -JimN

So, you can do what you've linked to - I have something similar on my boat from the PO, and it works well, but I worry about mechanical failure (i.e. the plastic breaking) causing engine damage someday while cruising down the lake.

You can use the fake-a-lake concept, where you attach the garden hose to what's essentially a toilet plunger, and attach it to the bottom of the boat (what JimN is referring to above). Simple, not quite idiot proof (it can dislodge from the water intake when you're not watching), and reasonably popular.

Others have removed the hose going into the raw water pump, and attached a new hose dropped into a 5-gallon bucket of water, normally kept full with the garden hose. At any engine speed above idle, you'll note that the garden hose does not keep up with the water sucked in by the raw water pump. The 5 gallon bucket assures that you can rev the engine (at least for a bit) without running it short of water.

If you want to reduce the mess, you can put a plastic kiddie pool under the exhausts to catch the water coming out of the engine, run the intake hose and garden hose into the kiddie pool also, and have a reasonably closed-loop cooling setup. I don't guarantee what happens when the water eventually heats up to 180 degrees, however. Having 20 or 30 gallons of boiling water sloshing through the garage might be a bit of a safety hazard if the pool collapses.
