This is a simple one that I couldn't find on any of the forums.
I need a fake-a-lake to allow me to diagnose audio noise that only presented itself when the boat was running, this is how I did it.
I purchased all parts at home depot which consisted of the following
1.5 x 1.25 coupling
1.5 pvc 45
1.25 x 1" NPT pvc coupling
1" NPT x 1" hose barb
3' x1" clear tube
I removed the outbound side from the strainer and slid the 45* over that. Next I slid the coupling with the hose barb into the 45 and attached the hose to that. Finally I filled the storage container with water and left the garden hose running. Worked well but keep in mind under throttle a garden has trouble keeping up, it's important to use a large reservoir.
If you do this and blow your motor up its on you, I take no responsibility. This is simply what I did that worked for me.
