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.
1 Bow-mounted trolling motors should run at least 5 inches (12.5 cm) below the water level to allow for rough water. 2  If you fish from a standing position while running the motor, a depth of 12 inches (30 cm) is recommended.. 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.
