DREWFAB DF1132-100 Jet Pump Brace & Driveshaft Loop | Adjustable Billet Pump Support for Jet Boats

The DREWFAB DF1132-100 Pump Brace / Driveshaft Loop delivers the two essential features every high-performance jet boat needs — hull stiffness around the intake and a built-in driveshaft safety loop.

CNC-cut from ¼″ billet aluminum, this pump brace is designed to be universal and fully adjustable, accommodating widths from 23-1/4″ to 26-1/8″ and various bolt patterns. The flange holes are slotted for easy alignment, and the brace height is adjustable for a perfect fit across multiple hull setups.

The integrated driveshaft loop includes a removable top collar held in place by two 1/4-28 button head screws (apply a drop of blue Loctite — snug only, do not overtighten). The brace provides exceptional rigidity to minimize hull flex and improve thrust transfer while adding an extra layer of safety around your driveline.

Guaranteed to bolt directly to a DREWFAB 5-degree intake, this brace has also been tested with stock Berkeley intakes and similar configurations.
