Jet Dynamics would like to introduce to you the shaft-shielding toploader. The Jet Dynamics toploader is a unique and patented design. Unlike other intake grates, the center bar shields the pump shaft from direct water impact. The ramp delivers water to the impeller without hanging below the keel more than half an inch.

This patented design eliminates cavitation during acceleration, and eliminates water being blocked from the pump by grate bars in a hard turn, this makes for a safer and better handling watercraft.

"how it works" section.
