Can you run a Mercury outboard out of water?

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.

Should you leave an outboard motor out of water?

Should I leave my engine up or down? Simply put, if you are leaving the boat in the water, leave it in the up position to avoid growth. If you are leaving it out of the water, trim it down to drain the water and protect the Power Tilt and Trim seals from the sun.

How long can you run a boat on muffs?

Bag and Muffs: Engine should be vertical, run no more than 800-900 rpm in neutral for 15 minutes with the prop removed. Be sure the engine is receiving cooling water (by checking the overboard indicator).

How to troubleshoot a Mercury outboard engine?

If your engine has a battery, make sure it is charged up before use; verify the battery connections are clean — as corroded connections can keep a Mercury outboard from starting. Stalling, Power Loss and Excessive Vibration Outboard motors require that you start them up and hold the gas until they can idle on their own.

What happens if you 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. Some newer motors have built-in attachments that accept a hose nozzle.

Can you run an outboard out of the water?

Hello: Loudon. Running any outboard motor, when it is not submerged in water or without the motor flushing device installed on the intakes with water running through it, can very quickly over heat the engine. I would not suggest deviating from the manufacturers advice. Doing sowill prove to be harmful to the engine and very costly to repair.

How many horsepower does a Mercury outboard motor have?

Mercury Marine, based in Wisconsin, has been making Mercury outboard motors in two- and four-stroke versions ranging from 2.5 to 350 horsepower for more than 75 years, though the company’s first motors did not have as much horsepower as some of its current motors.

Why is there no Pee hole on a Mercury outboard?

In a complete failure, small pieces of the impeller will travel up into the engine and clog the water passages. This will result in parts of the engine not getting cooling, and ultimate self destruction. Even if it get’s caught in time, it takes a teardown of the engine to retrieve all the lost pieces and clear the passages.
