Start the outboard motor with the normal throttle and choking procedures you use in the water.

How to run a boat motor out of the water. One way to run a boat engine out of water to check its functionality is. A boat motor should never be run without water running through it to coll the engine. How To Start an Outboard Boat Engine Out Of Water Starting an outboard boat engine out of the water can be done by using a tool called a Moeller Flushrite Boat Motor Flusher.

This tool is designed to look like ear muffs so that it can firmly attach itself to the inlet vents on the motor. Easy Step-by-step Guide to Start Your Inboard Boat Engine Out of Water. Prepare your boat and tools.

Attach the water hose to the flusher. Inspect placements and attachments. Turn on the water then the engine.

Most inboards have a flushing connection on the engine to connect a garden hose directly to. Fill the hose connected to the pump inlet with water so the pump picks up water quickly and gets lubricated quickly then shove the hose into the bucket making sure the pump continues to pick up water. Check water flow at exhaust to make sure all is working as it would if the boat was in the water.

Turn the water source on. Allow the air pockets to work their way through the muffs. Allow the water to flow through the muffs into the outdrive for 10 seconds before starting the motor.

Living in Utah Jared Curtis graduated in 2005 with a Bachelor of Science degree from Utah Valley University in. How long can a motor run out of water before impeller damage. If you ever notice how tight the rubber impellar is packed into that stainless steel cup then you know it wont take long for it to bulid up enough heat to damage it.

Id say running dry for 20 seconds would most likely fry that impellar. Better change it and not take a chance. Start your engine turn the steering to full lock and check if you can see water spraying out of the exhaust reliefs just below the lower engine cowl at the back of your engine If water is spraying out you now know your water pump is working If there is no water spraying out from the exhaust reliefs then yep start hollowing for a tow.

Never start your engine out of water unless you are using an external lower-unit flushing adapter commonly known as ear muffs designed for your type of outboard motor not the integral Freshwater Flush Adapter found on some engines to provide cooling water from a garden hose. Otherwise you could damage or seize the engine. Never run the motor of your watercraft out of the water.

While your Sea-Doos ROTAX engine features a closed-loop cooling system similar to that found in an automobile to ensure a consistent debris-free source of cooling liquid that liquid is cooled as its passed through internal channels in the crafts ride plate the rectangular metal plate covering the jet pump. If the boat has a fuel flow monitor set it to read in miles per gallon which will measure when the engine has reached the happy trimrpm balance. But dont go by this alone because slower speeds might show better fuel economy but will require the motor to be run longer which will age it more.

Make sure that a steady stream of water flows out of the water pump indicator hole as you continue flushing the motor for 3 to 5 minutes. This will be sufficient to flush the engine. Stop your motor turn off the water remove the ear muffs from the hose and stow them properly.

Put it in the water so the engineoutdrive is in the water but make sure the boat is not floating off the trailer. You want to make sure the boat is started and everything is properly working before you release the boat from the trailer. Run the Blower - This will evacuate the engine compartment and make sure there an no explosive fuel.

Start the outboard motor with the normal throttle and choking procedures you use in the water. Set the throttle to a fast idle about 1500 rpm if you have a tachometer with the gear disengagement feature active. This feature allows you to set the throttle to any point without engaging forward or reverse gear.

Put the boat on a trailer with the engine tilted down. Fit the bag around the gearcase. Fill the bag or bucket with water.

Make sure you cover the cooling water inlets. Start the motor to pump water out of the reservoir. The hose is responsible for maintaining water levels.

Dont leave the engine unattended as you watch the water flow freely. Start the motor and set the throttle to idle. Check to see that a steady stream of warm water runs from the outlet port.

Hot water water dribbling out or no water can mean the outlet tube is clogged or the impeller pump is failing. Turn off the motor immediately and unplug the. The more complexity the more likely it is to fail.

You can buy muffs that attach to the leg with water supplied by a hose. You can run an outboard for a very short time out of water but the impeller is running dry and will shred very rapidly. Running for 30 seconds without water will fry your raw water pump impeller.

You must insure that you have a water source into your raw water pump via filling the strainer with a hose AND a water source to lubricate the cutless bearing located within your p strut which is normally lubricated by flowing water. And since most shafts except the dripless PSS style rely on water drips to lube the prop shaft you should also figure out how to supply water. The hose attaches on one side and also routes water around to the other side as well via a small hose.

Also if it has nose cone water inlets like the 30L Mercs you should use a seal for those inlets. The nose inlet seal is mercury part number 881150Q 1 - FLUSH KIT Seal. Turn the water on full first then crank the motor.
