    im still curious how low yall have these aerator pumps mounted in order to get prime without the scupper and forward motion method the stock system requires...

    The trick is to have a constant uphill travel all the way from the thru-hull to the pumps outlet. If the pump is below the waterline, and air is allowed to pass through it and out the outlet, then the pump will prime without forced induction by a scoop.

    If you have the bilge depth, mount the pump directly on top of the ball-valve. If not, then use a 90* elbow between the t-hull and valve, then the pump. Just be sure to keep that upward travel. If the elbow is higher then the pump body, then an air pocket will be trapped in the top of the elbow.

    Old enough to know better, young enough to do it anyway.
