Bob's Machine 319-200000-NOPC Reversible 5 Degree Transom Wedge, BIA Bolt Pattern, Cast Aluminum, Sold as a Pair

The Bob's Machine 319-200000-NOPC is a reversible 5 degree transom wedge built to correct trim angle on outboard and sterndrive installations. Constructed of cast aluminum, it resists cracking and holds up under continued marine use. The wedge can be installed to provide either negative or positive trim: negative trim is most commonly used when the bow will not come down enough due to the angle of the motor, while positive trim suits boats needing the opposite adjustment. It fits all motors with a BIA bolt pattern, making it a straightforward retrofit for correcting a boat's running angle without changing the motor mount itself.

Each wedge measures 3 inches wide by 14 inches in total length, and is sold as a pair to outfit one engine. Because the wedge adds thickness between the transom and the motor mount, longer mounting bolts are required: 1.5 inches longer on the thicker side of the wedge and 0.25 inches longer on the thin side. This 5 degree version sits between the lower-angle and higher-angle wedges in Bob's Machine's transom wedge lineup, giving installers a mid-range trim correction option.
