How long can you run a boat motor on muffs?
For larger engines, use the flush port or a set of flushing muffs. Water pressure should be set to one-half or more to ensure adequate flow to the intakes. The engine should be run for five to 10 minutes.
Should you flush your outboard motor after every use?
Most outboard manufacturers recommend a freshwater flush after every use in saltwater to clear the cooling passages of salt residue and scale that can accumulate and impede the flow of vital cooling water through the engine.
How do you backflush Mercury outboard?
All you have to do is lower your engine to the vertical position, hook up a hose to the conveniently located flush connector and let the water run for 10 minutes – you don’t even have to start your engine.
Can you put an outboard motor in gear out of water?
Yes, you can put it in gear. VERY LOW to show that the prop will in fact spin but you can not rev the motor “muffs” will not be able to suck in enough water.

How to Cold Start a Mercury Outboard Motor Put the motor in neutral and fast-idle. Push in the key, turn to start, and hold it in until the outboard starts up. Release the key. If the motor begins to stumble at this point, bump the key again to engage the choke & primer. Repeat until the engine is running smoothly.
Where should water come out of an outboard?
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. While this can be alarming, it is perfectly normal for those models.
Can I test outboard motor out of water?

What happens if you don’t flush your outboard?
What we find is if you do not flush your motor as per the manufacturer’s specifications you will over time get a build-up of residual salt, and that salt will crystallize in the water flow galleries and being pressed against the alloy structure of the head they will slowly corrode and pit.
Can you use a saltwater motor in freshwater?
Saltwater motors are more robust (from a components perspective, corrosion resistance) than non-saltwater rated motors. The only reason is the expense of a salt water motor vs freshwater. If you already have it, it will work fine in fresh water.
