Hedda Woody Hopper Boater here. A little birdie has told me one of you out there broke the golden rule of flathead engine water flushing. You hooked up your hose directly to the water pump! Oh….
Now to some of you, you may be wondering what I am talking about. Well, for us here in brackish water we flush the engine a lot, for those of yous on fresh water lakes, you may use it to test an engine on dry land. Either way the issue is the same, and if you hook up the hose to your water pump, two things for sure will happen.
1. Head Gasket failure!
2. Water pump failure
And it happens fast. I am sure there is some sort of engineering term for this, but as the say’n goes. IT’S SUCK NOT BLOW! What? You will remember it now won’t you. So how are you supposed to do it?
One, get a 5 Gallon bucket. You need one anyway for other things.
Two, hook up your hose and run it to the bucket. NOT THE ENGINE
Three, Tie in a smaller hose to the area below your water pump. You will have to have a shut of valve. Easy hardware store stuff.
Four. Fill the bucket with hose water
Five, run the hose from the engine in into the bucket filled with water, keep the water running, the hose will SUCK the water into the engine.
That’s it, watch the pump SUCK the water out of the bucket. And you will have a happy ending. Yeah, walking a thin line here. But you will remember this now. Here is a short video of how it works.
