What happens if I don’t flush my outboard motor?

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.

Is it necessary to flush an 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.

Do you need to flush an outboard motor with antifreeze?

To prevent freeze damage, prior to winter storage, many owners simply drain the cooling water out of their outboards. However, while it might seem like “overkill”, we recommend flushing your motor with antifreeze. This will prevent residual water from turning into ice and causing damage during a hard freeze.

How long should you flush your outboard?

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.

What happens if you don’t break in outboard?

There can be some variables depending on the manufacturers, but for outboard engines, it is basically all the same. Regardless of the brand. Yamaha, Honda, Mercury, or Suzuki, they are all basically the same. … The rule of thumb for most marine engines are 10 hours for the break-in period.

How long can you run a outboard 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.

Can you put an outboard 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. The problem is if you go from forward to reverse without letting the prop stop spinning in neutral first.

Should you winterize an outboard boat motor?

If you want your engine to start in the spring and last you many years and plan on not using your engine all winter, you do have to winterize an outboard motor. Winterizing the engine helps to prevent damage during disuse, which is the chief cause for engine failure. Failing to winterize may lead to complications.

Is fogging a boat motor necessary?

Yes, to the above. Any engine should be fogged when it will not be used for a while.

How much does it cost to winterize an outboard motor?

If you bring your boat to a shop to have it winterized, you can expect to pay between $300 and $400.

Should you leave your outboard up or down?

It’s best to tilt your outboard up when leaving your boat in the water to prevent marine growth from forming and from corrosion eating away at its metal parts.

Is an engine flush a good idea?

Is an engine flush necessary? A good engine flush can help loosen deposits and dissolve sludge, returning your engine to like-new condition. However, in old engines with high miles, the engine sludge may be the only barrier keeping engine oil from seeping through worn or cracked seals.

Is it bad to run a boat motor out of water?

Flushing a boat motor by running it out of water is a routine maintenance task. Running the engine without a water source for any length of time will cause damage, so you’ll need to attach a hose to the motor’s water intakes. … If your motor doesn’t, you’ll need a set of motor flusher muffs.

Do outboards get faster after break-in?

I do not recall ever seeing a significant speed increase after breaking in a new outboard. However, I have seen significant speed increases as I learned how to optimize trim, pitch and mounting height. I don’t think you’ll see much of a speed increase after break-in.
