An outboard bracket for your boat improves the line of thrust, center of effort and floatation. Enlist a few friends to help you install an outboard bracket. If you don’t have experience or enough knowledge on Fiberglas, it is best to contact a skilled repairman to ensure that no damage happens to your bracket or your boat.

Step 1 – Prepare the Outboard Bracket

Before trying to install your outdoor bracket, make sure that you have already sanded it. Prime it up and apply pain in your desired color. Use a rag to wipe away dust from sanding before starting to prime your bracket. Place the bracket on top of layered old newspapers to ensure that paint won’t drip in your working area.

It is also best to work indoors to ensure that your engine won’t get wet from unexpected rain.

Step 2 – Check up the Transom

The transom must have enough strength. To check up on this, you might need to get a fiberglass expert. Add fiber-glassed plywood to the insides of the transom, if needed.

Step 3 – Mark the Centerline

Start by measuring the keel centerline using a framing square. Mark the transom depending on the size of your motor. If you are using a 20-inch motor, the mark should be 19 inches. Remember that the marks on the boat’s transom must fit that of the bracket.

Drill holes for your stainless steel boats if necessary. Remember that the bolts of your bracket must be at least 10 inches apart to provide strength. Tape the areas where the outboard bracket would be sealed (including the nut areas) to ensure that the sealant won’t soil the paint of your boat.

Step 4 – Apply Sealant

Use a reliable marine sealant to fill up holes that are too loose for your bolts. Also, apply a generous amount of marine sealant around the nuts to ensure that no water would go through it. Check up the seam of the bracket to the transom. Make sure that you also apply marine sealant on these areas.

Step 6 – Get a Backing Plate

Install the aluminum backing plate once you have double-checked the sturdiness of the outboard and the placement of the motor.

Step 7 – Inspect for Any Possible Opening

Let the sealant dry completely as instructed by its manufacturer. Take off the masking tape that you have previously placed. Use a flashlight to check on any possible opening that you have missed. If you see one or two, tape on masking tape around the area and apply the sealant. It might also be necessary to double-check on the areas where you have already applied marine sealant.
