How to Install a Gasoline Outboard Motor and Water Separator?

Outboard motor gasoline and the water separator can be a great investment for your boat. The boats are subjected to a lot of water and mist on the bow when cruising or moving on the plane, and the marine gas tanks regularly collect condensation inside and send water through the system. fuel. The water corrodes the metal parts, destroys the lubrication and, in some cases, if they are allowed to enter the cylinders, stops the engine. The gas and water separators trap unwanted water in the fuel system, allowing it to be discarded during routine maintenance. Our best selling outboard engine guide will help you to choose the best one for you.


  • Trailer your boat and take it to an ideal location for installing the fuel water separator. Turn on the ignition switch and close the engine fuel valve. Place a good amount of rags underneath the gas tank line that leads to the outboard engine compartment. Open the deck hatch if your fuel line runs underneath. Look for a mounting location near the holding area, where you can screw a hull mount such as a runner or chine.
  • Use a jigsaw to cut a 1-inch square piece of marine plywood if you do not have a proper mounting location on the hardwood. Glue the plywood square to the hull with marine epoxy glue, midway between the gas tank and the engine fuel inlet. Let it dry. Position the kit holder on the wood surface and use a pencil to mark two drill holes on the mounting wood. Use a drill and a little bit to drill the 1/2 inch holes in the wood.
  • Screw the bracket into place, using the screws provided as a kit. Dab a little silicone sealant on both nozzle fittings kit and screw them into the flange of the fuel-water separator, by hand. Tighten the fittings with a spanner. Hold your fuel tank online and cut it in half with cutting pliers. Let the gas run on the rags. Place two hose clamps on each end of the fuel line, for a total of four clamps.
  • Push the fuel lines firmly onto the nozzle fittings. Loosen the collars enough to push them onto the hose nozzle fittings. Tighten the four clamps with a flat screwdriver. Unscrew the bottom separator bowl and fill it with gasoline in a cup, for priming purposes. Screw the bowl back onto the separator, hand tight only. Wipe up any spilled gas. Remove the rags.
  • Carry the boat with water, or immerse the lower unit in a barrel of water. If you have a muff flush device, connect it to a garden hose and install it on the water inlet holes on the bottom unit. Turn your power cut switch to the position. Activate the engine fuel valve. Depending on your type of starter, pull the starter rope back or turn the ignition key to start the engine.
  • Run the starter repeatedly in short jolts, allowing the fuel to build in the lines. Look for leaks in the fuel line connections when the engine starts. Remove your tools and clean injectors of an inboard engine.

Tips and Warnings

  • Do not smoke anywhere near this installation procedure. To be sure, remove the battery from the boat if you have one on board.
