If your outboard idles rough, stalls under load, or refuses to start in the morning, check the fuel before you check anything else. Water in the fuel is one of the most common breakdowns on small boats around Kuwait, and you can catch it yourself without a mechanic.
The tank breathes with every temperature change. It cools overnight and pulls in humid air, then heats up during the day. That moisture condenses on the inside walls and runs down to the bottom, where it sits because water is heavier than petrol.
Add Kuwait's humidity and a fast fill from an old pump or an open drum, and you have a steady supply. Over months, a layer of water builds in the lowest corner of the tank and the engine pulls it before it pulls fuel.
Water rarely kills an engine in one go. It starts small and grows. You get a rough idle, a note that changes when you touch the throttle, and a stumble the moment you accelerate. Starting after a short stop gets harder, especially first thing in the morning.
In worse cases the engine dies while you are underway, which is dangerous in a channel or near other boats. If the symptoms come and go, do not blame old fuel and move on. Drain the bowl and look.
Shut the engine down and close the fuel valve if you have one. Gloves on, small container under the filter, then open the drain screw at the bottom of the bowl. Let it run slowly and watch what comes out: clear or cloudy water first means you have found the problem.
Next, remove the bowl and wipe it clean, then look at the element. Dark colour, visible debris, or a soft feel when you pinch it all mean replace. Do not dry it off and refit it. A new element costs far less than a lost day on the water.
Change the element at the start of the season, after any fill you are unsure about, and any time the bowl collects more water than usual. Keep a spare element, spare seals, and the right filter wrench in the toolbox so a dirty filter never ends a trip.
Before you launch, check the sea state in the B7R app. If it is blowing, put the refuel and the filter check off to a better day.
When you fill up, keep the nozzle touching the filler neck and go slowly. Avoid open drums. Do not leave the tank half empty for long periods either, since a full tank leaves less air inside to condense.
For storage, fill the tank before you park the boat, seal the cap properly, and put a little grease on the seal. After the first run of the new season, check the bowl again even if everything felt fine.
Water in the fuel is a small problem caught early and a serious one caught offshore. The B7R app gives you sea state, tides for Shuaiba and Shuwaikh ports, a fish guide and a catch log, and it is free on Google Play: download the app.
