Kuwait's summer heat does more than make a day on the water uncomfortable. High air temperatures, heavy humidity and warm seawater put real pressure on your engine and fuel system. Most heat-related breakdowns are preventable with a few checks before you launch.
High humidity means the air carries heat away less effectively, so cooling weakens exactly when the engine needs it most. A boat sitting in direct sun without airflow turns its engine bay into an oven before you start.
Warm sea water matters too. A raw-water cooled engine needs a temperature gap between water and engine. When the water is already hot, that margin shrinks and the system runs near its limit.
First, do not trap the engine in a sealed box. Confirm the vents are clear of dust, rags and gear so air can flow. If you can open the hatch slightly while idling or drifting slowly, temperatures drop fast.
Next, check the water flow. An old or cracked impeller reduces flow quietly, and heat builds before you notice. Open the hatch and watch the tell-tale stream. If it is weak or intermittent, stop and inspect it.
Never ignore the overheating alarm. When it sounds, shut down and investigate instead of risking the entire engine.
Heat makes petrol evaporate faster, especially in a partly empty tank. Vapour can interrupt fuel flow, a problem known as vapour lock, leaving the engine stalling or refusing to restart.
The tank also breathes as temperatures swing. Overnight cooling draws in humid air, which condenses into water, and even a little water causes rough running. Filling the tank before you launch reduces vapour space and condensation.
Old fuel loses its punch over time, and heat speeds that up. Store only what you need, use fresh fuel, and replace the fuel filter if it looks discoloured or restricted.
Heat raises resistance in connections and shortens battery life. Inspect terminals for corrosion and salt, then confirm every plug is seated. Carry a portable jump starter, and heat cracks wiring, so check it before each trip.
Leave at first light, when the air is cooler and the wind calmer. Avoid the midday peak when you can. If you cannot, take shade breaks and drink water often. Your crew needs heat protection as much as the engine does.
Before you head out, check sea state and weather in the B7R app, and pack water, sunscreen and a hat. Stay ready for the unexpected too: the SOS emergency button in the B7R app gives you a fast way to call for help.
Make planning a habit and keep the B7R app with you: tide times for Shuwaikh and Shuaiba ports, sea state and weather, the fish guide, catch log and seasons, and navigation tools. It is free on Google Play. Download it here: https://play.google.com/store/apps/details?id=com.q8dm.b7r
