Boats With Front-Mounted, Raised Pedestal Fishing Seats; Wave And Wake Jumping; Impact With Underwater Hazards - Mercury MR504LB3 Manual

Boats With Front‑Mounted, Raised Pedestal Fishing Seats
Elevated fishing seats are not intended for use when the boat is traveling faster than idle or trolling speed. Sit only in seats
designated for traveling at faster speeds.
Any unexpected, sudden reduction in boat speed could result in the elevated passenger falling over the front of the boat.

Wave and Wake Jumping

Wave or wake jumping can cause serious injury or death from occupants being thrown within or out of the boat. Avoid wave
or wake jumping whenever possible.
Operating recreational boats over waves and wakes is a natural part of boating. However, when this activity is done with
enough speed to force the boat hull partially or completely out of the water, certain hazards arise, particularly when the boat
reenters the water.
The primary concern is the boat changing direction while in the midst of the jump. In such cases the landing may cause the
boat to violently veer in a new direction. Such a sharp change in direction or turn can cause occupants to be thrown out of their
seats or out of the boat.
There is another less common hazardous result from allowing your boat to launch off of a wave or wake. If the bow of your boat
pitches down far enough while airborne, upon water contact it may penetrate under the water surface and submarine for an
instant. This will bring the boat nearly to a stop in an instant and can send the occupants flying forward. The boat may also veer
sharply to one side.

Impact With Underwater Hazards

Reduce speed and proceed with caution whenever you're driving a boat in shallow water areas or in areas where the waters
are suspected of having underwater obstacles that could be struck by the underwater drive components, rudder, or the boat
bottom. The most important thing you can do to help reduce injury or impact damage from striking a floating or underwater
object is control the boat speed. Under these conditions, boat speed should be kept to a minimum planing speed of 24 to 40
km/h (15 to 25 MPH).
Striking a floating or underwater object may result in an infinite number of situations. Some of these situations could result in
