On many outboards, you can simply put on the muffs and start the engine. You should see a steady stream of water coming out of the holes on the top of the engine. However, some brands do pump out a stream, but it might not look steady.
Is water supposed to come out of outboard?
Yes, water should come out of the prop hub with the exhaust.
Where is the water intake on a boat motor?
If clearing the nozzle doesn’t improve the flow, that indicates either restricted cooling system flow or a weak water pump. The water intake for your engine’s cooling system is located forward of the propeller on the lower unit housing.
How do I know if my outboard water pump is bad?
Signs of a bad boat impeller are either boat engine overheats when you try to accelerate, loss in impeller vanes flexibility, physical wear & tear like cracks in impeller vane roots, melted or worn of vanes. Even if you see less or no water coming out of tell-tale, it might be due to a bad impeller.
Where does water come out of inboard outboard?
Fresh seawater is normally drawn by a belt driven pump from a thru hull fitting in hull of boat on inboards, or by water pump in stern drive through the lower unit water passages on an inboard/outboard, and then exits the boat through the exhaust.
Why is my outboard not pumping water?
There are three reasons your outboard motor’s impeller won’t pump. The first is that the water stream fitting — the outlet hole for an outboard motor’s cooling system — is clogged. … The second is that the water inlets are clogged; no water is getting to the pump, so it isn’t pumping.
What is a tell tale on an outboard motor?
A telltale hole emits a small, visible stream of water after it has passed through the powerhead, to help indicate that cooling water is flowing. Tip: If water should stop flowing from the telltale hole on your outboard, or if the stream becomes weak, carefully check the outlet tubing for obstructions.

How often should you change the impeller on an outboard motor?

What should the water pressure be on an outboard motor?
Minimum pressure at wide open throttle should be about 12PSI. If you are running WOT and trimmed out properly, and still getting 30 psi, I’d say your engine is too low. Raise it on the jack plate until you either gain rpm with no increase in speed, or water pressure drops below 12psi.
Can you put an outboard motor in gear out of water?
There is no difference putting the motor in gear at idle in or out of the water. The prop shaft will actually spin the prop with less initial resistance than if the prop was in the water.
