DIY Outboard Engine Bracket

Updated April 17, 2017

Outboard motors are designed for boats navigating on small rivers and streams for transportation or recreation purposes. Inboard motors can be used on small rivers and streams but are not as useful due to their cumbersome manoeuvring mechanisms. However, you can convert your inboard boat to an outboard by removing the inboard, adding an engine bracket and bolting on an outboard. The process of making your own outboard engine bracket requires attention to detail.

Lay one medium stainless steel board flat on the ground and bend the edges up 90 degrees, 5 inches from the two sides. Drill five holes into each of the sides.

Drill five holes on one of the sides of both of the small stainless steel boards. Drill two holes, one at each corner, on the other side. Match up the five-holed sides with the medium board and bolt it on.

Drill two holes in each stainless steel bar, each 1 inch from the end. Bolt two of the bars to the top -- farther -- two holes. Drill 1-inch holes at the centre of the two leftover bars. Bolt the two bars as you did with the first two at the closer of the two holes.

Lay the second medium board on the floor and drill one hole in each corner. Bend the edge as you did in Step 1. Bolt the bars to the holes at the corners and apply lubricant on the bolts.

Bend the long aluminium pole 90 degrees at 1/3 and 2/3 of the total length and drill a 1-inch hole facing outward 1 inch from the two ends. Hold this up to the stainless steel bars with holes in them and match them up. Push the stainless steel pole through and weld the outside of the pole to the bar.

Drill holes in the backboard to bolt onto your boat's transom. Drill holes in the front board to attach your outboard motor.
