The wheels must face towards the boat tubes and be as far apart as possible (it brings more stability when moving the boat around) and clear the boat tubes by about one inch so they don't rub against the tubes when being raised or lowered. The wheels must also clear from the bottom of the boat by about one inch when placed in their lowered position.
Once you have determined the mounting positions for the brackets which should be straight up and down on the transom and about 6-8 inches up from the bottom of the bracket to the bottom of the boat. Mark where to drill the 5/16” holes (drill bit not included). This is best done by separating the leg assembly from the bracket. Double check everything again before drilling any holes! Holes and transom must be vertical.
Use the supplied washers and lock nuts on the bolts on the inside of the transom to secure the brackets to the transom and then cap them with the supplied acorn nuts to protect your boat when rolled up.
