Operating In Freezing Temperatures

If there is a chance of ice forming on the water, the jet drive should
be removed and drained completely of water. If ice should form at
the water level inside the outboard driveshaft housing, it will block
water flow to the engine causing possible damage. Do not start the
engine until the ice is clear.
