An outboard motor should never be operated without a source of water entering the inlet screens to supply the water pump. Without a source of water for lubrication, the water pump will be the first to be damaged, followed shortly thereafter by the engine from a lack of cooling.
How long can you run a boat engine without water?
How Long Can You Run A Boat Motor Without Water? You are not supposed to run your boat motor without water, but if for some reason you must, between 2 and 10 seconds is the max time.
Do boat motors need to be in water to start?
As it turns out, you can safely start your boat engine while out of the water as long as you have a properly connected water supply, like a garden hose attached to the water intake vent.
Do I need to flush my outboard motor?
Most boaters know it’s imperative to flush an outboard with freshwater after boating in saltwater or brackish water. Failure to do so can allow corrosion to take hold in your motor’s water passages, compromising your cooling system and shortening the life of your engine.
What happens if you run an outboard out of water?
Without water to cool the engine, it will rapidly overheat inside of the cowling (the cover) and will likely seize up or blow a head gasket as the oil will heat up to a point that it loses its lubricating properties.
How long should I flush my outboard motor?
Flush for at least five minutes at an idle speed, with the engine in a vertical position. When using the flushing port, it is not necessary to run the engine. Keep the engine vertical after flushing so that all water drains from the powerhead.
How much water should be coming out of outboard?
Re: how much water
The thermostat will not open till the motor reaches around 140+degs. and water should come out the pee hole then as the stats open up. There should be an exhust/water port on the midsection back side that should have water spiting out of them at idle and till the stats open up.
Why is my outboard not spitting water?
The water pump impeller is the cause of most water circulation and overheating problems. The impeller is essentially a small, round disc with spinning blades used to move water through the circuit of the outboard motor. When the impeller is broken, it stops the supply of water to the engine and results in overheating.
Can you run a trolling motor out of water?
Can You Run a Trolling Motor Out of Water? The short answer is, yes. The motor will run just as well out of water as if it were submerged.
What happens if I don’t flush my outboard motor?
Full of salt build-up and even sand which is a result of not only not flushing the motor correctly but also running the motor through the shallow water pumping a lot of sand up through the outboard.
How often should you start your outboard motor?
A few hours every week keeps the motor in better shape than using it two or three full days every month. The more often it gets used, the better it will run, just like any vehicle. If it’s left sitting idle at the marina or in a garage for the majority of the time, parts tend to go bad faster.
