Adjustable wrench

The boats with its trailer rests on boat trailer rollers or bunks when idle, as they provide support to keep the boat in its position, while traveling. It is important to ensure that the boat is working under our control, hence the rollers must be adjusted timely to the strongest part of the boats hull. Given below are a set of steps to adjust boat rollers.

Step 1 - Careful Evaluation

Keep a 4 foot spirit level above the boats casement where the outboard motor is placed. With the help of 2 assistants hold the boat steadily balancing on its keel. Let the helpers watch the level during adjustment and inform you if the boat begins to lean onto one side of the trailer.

Step 2 - Dismantling

Carefully remove the nuts holding the bunks and rollers except the rollers or bunks underneath the keel, such that the bunk or roller move away from the hull. Make use of the adjustable wrench in this process.

Step 3 - Positioning the Bunks

Slowly lift the outermost bunk or roller from left side to the hull and place it carefully against the hull in an unbreakable location. Let one of the helper hold the bunk in position until you fix the bolts that hold the roller or bunk appropriately. Perform the same process once again on the right side for all the remaining bunks or rollers except the one at the keel.
