This will cause the freshwater recirculation pump on the forward end of the engine to stop turning. On an inboard, check the V-belt.Ī sudden high temperature rise can be caused by the breakage of the V-belt on an inboard with an enclosed cooling system.
Often on outboards and inboards, just shifting into reverse for a moment will clear the debris over the intake. On outboards, plastic or even seaweed over the cooling intake vents will prevent water from reaching the engine. An inboard engine may suck a large piece of debris, such as a plastic bag, onto your strainer outside the hull, particularly if you're moving slowly. Debris in a raw-water strainer for an inboard is easily fixed by turning off the engine, closing the thru-hull valve, and cleaning the strainer. When debris blocks the cooling water intake or clogs the strainer and restricts water flow, failure to remedy the problem immediately can result in the destruction of the impeller and other more serious problems. Always wait until the engine has cooled before you work on it. Restarting at the higher temperature may ruin the engine. Usually the engine temperature will continue to increase after shutdown because it's no longer getting any cooling water. Turn off the engine immediately, if safe to do so.ĭo not restart until it cools down to within normal operating temperatures.
A voltage change at the gauge, as when you turn on the instrument-panel lights, could, in some installations, cause a slight increase in the temperature reading that has nothing to do with the engine. But if the cooling water is spewing out normally, check your voltage. You'll need to work through the next few items to find the problem. If the volume of water has diminished or if there's white steam (which may look like extra exhaust), not enough water is going through the engine to cool it. Check for cooling water coming out of your exhaust or the "pee hole" in the outboard. But often, a spike in temperature signals a temporary malaise that will have few long-term consequences if quickly remedied. Any of these normally require a good mechanic and can be pricey to fix. The worst possibilities include loss of compression because of damaged rings or valves, lubrication issues, main-bearing problems, misfiring, and more. Some are a serious threat, others are not.
Any number of things can cause your engine's temperature to spike.
