Timing of the test For all oxygen groups (i.e., Group I, II and III), initial testing must be done within the 30 days before the initial date of service. For Group II beneficiaries, recertification testing must be done between day 61 â 90 after the initial date of service.
Trolling motors are popular with anglers who want to be able to maneuver around a fishing area without disturbing the fish below the surface. When youâre searching for a new electric boat motor, keep these points in mind: 1  Most trolling motors operate on 12 volt, 24 volt and 36 volt circuits.
2. Slip the motor over the transom. The trolling motor should be placed as close to the center of the stern as possible without interfering with the operation of the main motor, if there is one. The top of the mounting bracket should be flush with the top of the stern.. Open the mounting bracket clamps. Transom-mounted trolling motors have 1 or 2 clamps built into the mounting bracket to hold the motor in place. Turning the clamps counterclockwise (to the left) will open them.
