    • Towers and pylons are designed to pull a single individual only. Section 5- Boating Rules Basic Boating Rules You should be aware of these rules and follow them whenever you encounter another vessel on the water. The rules presented in this manual are condensed and have been provided as a convenience only.
  • Page 16 • Meeting (you are approaching another vessel head-on) • Crossing (you are traveling across the other vessel’s path) • Overtaking (you are passing or being passed by another vessel) Using the following illustration in which you are the boat in the center, you should give right-of-way to all vessels shown in the red area.
  • Page 17 When two power-driven vessels are crossing each other’s path close enough to run the risk of collision, the vessel that views the crossing vessel to the starboard (right) side must give-way. If the other vessel is to the port (left) side, maintain your course and direction, provided the other vessel gives you the right-of-way as it should.
  • Page 18 There are three other rules to always remember when driving your boat around other vessels. When navigating in narrow channels, you should keep to the right when it is safe and practical to do so. If the operator of a power-driven vessel is preparing to go around a bend that may obstruct the view of other water vessels, the operator should sound a prolonged blast on the whistle or horn--four to six seconds.

  • Page 26 Gasoline Stabilizer should be added to the fuel tank when the boat is used infrequently or whenever your boat will not be used for two weeks or more. During storage always add Gasoline Stabilizer to reduce gumming or tank sludge. CAUTION ! Be especially careful when filling the fuel tank.
  • Page 27 IMPORTANT Use a gasoline with a minimum octane rating of 89. IMPORTANT Pay careful attention when filling the fuel tank. DO NOT overfill the tank! Fuel may empty through the fuel vent and damage the outside finish. Fuel Vent The fuel vent is a part of the gas filler neck. This vent is connected to the fuel tank via the vent hose, which releases gasoline fumes from the fuel tank.
  • Page 28 On GT Series models, the rear panel in front of the gas tank has a viewing slot so that you can see the actual amount of fuel in the tank. On REVO models, access to the fuel tank is easily gained through the floor panels on the V drive models and behind access panels located in the rear of the boat on Direct Drive models.

  • Page 48 This gauge indicates the approximate quantity of fuel remaining in the tank when the ignition is in the “ON” position. IMPORTANT DO NOT run the tank to empty. To prevent condensation from forming in the tank, it is recommended that the tank be filled when the gauge indicates 1/4 tank of fuel remaining.

  • Page 58 The rear tow eye can be used for tying up or for pulling purposes. Propeller The research and design team at Gekko has carefully explored and tested many different propellers and pitch angles for use on our boats. All tests indicate that the current propeller installed on your model is the best for the variety of boating performance required, whether skiing competitively or for pleasure.
  • Page 59 It is strongly recommended that your Gekko dealer be notified before changing the propeller. In general, changing to a lower pitched propeller may increase acceleration, but will decrease top speed. Changing to a higher pitched propeller may achieve higher top speed with a light load, while acceleration and power may decrease.

  • Page 129 REVO Trailers May Be Equipped With Torsion Axles Trailers equipped with a swing tongue permit easier storage by simply removing the vertical locking pin. Connecting the Trailer to Your Vehicle When connecting the trailer to your tow vehicle use the following procedure:...
  • Page 130 1. Raise the tongue with the trailer jack, position the trailer tongue directly over the 2” ball, and lower the jack until the tongue goes all the way down over the ball. 2. Press down on the latch until it locks on the ball with a “click.” If your hitch ball has an excessive flat spot on top, the latch may not engage properly.
  • Page 131 Doing this will secure the trailer to the hitch. CAUTION ! Confirm proper trailer connection prior to departure. Inadvertent release of latch pin could result in injury! Five-Pin Connector All Gekko trailers require a five (5) pin marine grade trailer wiring connector.
  • Page 132 Blue: Reverse Lights IMPORTANT Some Gekko trailers feature disk brakes. To make the brake lockout operative for easy reverse operation, the 5 wire (blue) on the wire connector needs to be connected to your vehicle’s reverse lights. This blue wire provides power to a solenoid that deactivates the brakes while in reverse.

  • Page 135 When launching the boat, back the trailer so the fenders are just below the water line. Start the boat and allow the engine to warm up for 1-2 minutes before backing off the trailer. IMPORTANT The depth of the trailer while launching and loading may vary from ramp to ramp depending upon the incline.
  • Page 136 Your local dealer can help you understand this, should you require additional assistance. IMPORTANT Before loading your Gekko, back the trailer completely into the water to wet the carpeted trailer bunks. This will allow the boat to slide onto the trailer easier and help prevent premature carpet wear.
  • Page 137 IMPORTANT Leaving the trailer too far into the water may cause the bow of the boat to hit the bow roller stanchion causing damage to the boat and/ or trailer. IMPORTANT The depth of the trailer while launching and loading may vary from ramp to ramp depending on the incline.

  • Page 139 Securing the Boat to the Trailer Connect the winch strap to the bow eye and tighten the strap with the winch until it is taught. This should be done before the boat is removed from the water to prevent the boat from sliding off the trailer while exiting the water.
  • Page 140 Rear Tie Downs Gekko recommends securing the back of the boat to the trailer with tie down straps. Tension the strap from the transom eye to the trailer eye so that the locking lever is at approximately a 90-degree angle. Push the locking lever down until it snaps into position.
  • Page 141 IMPORTANT When pulling the boat onto the trailer, be sure that it is centered on the trailer. Improper loading may damage the boat and could cause trailering problems. The distance between the boat and the wheel runner board should be equal on both sides.
  • Page 142 Bearing Buddy It is the owners responsibility to ensure that the wheel bearings are properly lubricated. To grease the trailer wheels, simply remove the metal cap shown above and pump marine wheel bearing grease into the exposed nozzle with a grease gun. CAUTION ! Wheel bearings must be properly greased for safe trailer operation and to prevent axle damage.
  • Page 143 It is the owners responsibility to ensure that the lug nuts are properly tightened. CAUTION ! Lug nuts must be checked regularly for proper torque to insure that wheels do not come loose during trailering which can endanger you, other motorists and cause damage to your boat and trailer.
