There are several features to be aware of when operating a Williams Jet Tender. First, a driver should review the owner’s manual before going out. Exploring the new tender will allow for proper preparation and instruction. Users will find navigation lights under the engine hatch as well as lots of useful storage on board. There are also drain bungs for draining the footwell. Drivers will find the fuel filler underneath the bow cushion. They will also find the battery on the front left side of the engine bay. Above the battery sits the fuse box for convenient access. If any warning lights illuminate, it is good for users to check the owner’s manual for reference.

Before Take Off

Before operating a Jet tender, users should be aware of several things. The jet propulsion system is always producing thrusts even when idling in neutral. This results in a constant slow creep forward. This feature allows the tender to maneuver at very slow speeds. This also allows it to spin around within its own length. To turn the boat while underway, drivers must apply thrust because there is no rudder. Not applying thrust while coasting along will reduce the ability to steer.

Starting up

To start a Williams Sport Jet, the driver must ensure the boat is in at least two feet of water. It is good to check the bilge beforehand for any water ingress or oil contamination. It is also useful to ensure the coolant level is between minimum and maximum level. The jet does not have a separate battery isolator. Drivers can turn the ignition key to the right to power up the boat. It is best to let the bilge blower to run for 2 minutes to remove any residing fuel vapors. During this time, the user can check for any loose ropes or debris that could entangle in the jet pump intake. The shift lever should be in neutral. The safety lanyard should also remain attached to both the driver and the boat.

Take Off

After these steps and checks, it is time to take off. To prepare for takeoff, drivers will press the start/stop button to get the engine going. One last test before taking off is to check the safety lanyard. If the user pulls out the lanyard, it should trigger the emergency kill switch. As long as this works, drivers can start up that engine again and head off.
