How to test a boat motor out of water. Tips for testing a boat motor out of water. Ensure that you consult the manual before attempting to test the boat motor out of water. The manual specifies the location of the water intakes and other specifications that will be useful to your work.

The manufacturers instructions are essential in handling any aspect of the boat. Attach the garden hose to the muff plunger. Ensure that the hose is secure and tight.

Turn on the garden hose all the way to confirm that there is a solid flow of water then turn it off for now. While your boat is resting on a trailer go underneath and locate the water intake hole.

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. You can test an outboard motor without access to a boat or ocean.

Simply mount it to a sturdy platform place a big bucket underneath it and fill it with water so the propeller is fully submerged. Clean out the gas can of old gas and oil mixture because it may be water. 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. Find your boats water intake and place the motor flusher over it. Get underneath your boat and find the water intake.

The intakes location can be different depending on your engine and boat so refer to your manual for this information. Once you find the intake place the cup of your motor flusher over it. Next adjust the motor flushers leg to a length that reaches.

This usually means the rudder is poorly designed and creates turbulence rather than channeling water. Finally idle forward turn the wheel hard over and then push the throttle to the wall. Some poorly designed boats lay over so far on their beam that water pours over the gunwales.

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. Examine the exhaust for holes as this can allow water and exhaust gas into the interior space and bilge of the boat.

Also check that the engine coolers are working properly and the raw-water intake hoses are double clamped on each end. Test the engine oil for water grit color and odor. Fill the bucket with water from a hose or another bucket.

Take a hose from the engine raw water pump inlet and dip it in the water if you have a non strainer type skin fitting just ram a pipe into it. Start the engine and top up the bucket from a hose or another bucket as it empties -roughly 10 ltrs ish. Apply water-finding paste to a wooden dowel then insert it down to the bottom of the fuel tank and remove it.

The paste will change color if comes into contact with water. Water-finding paste is not particularly accurate and wont tell you whether if its water or phase separation at the bottom of the fuel tank. If the contents of the jar appear to have a clear bubble at the bottom gas floats on water remember there is some water contamination.

Siphon the water from the bottom of the tank. If phase separation from ethanol and water mixing this bubble will be a gelatinous white as shown in the photo you likely need to call an environmental services company to safely. The WOT test is done in three simple steps.

Find out your outboard or sterndrives WOT rating. Run your boat at WOT. Replace the propeller with a higher or lower pitch prop.

To get the most accurate result from the WOT RPM test there are a few things you need to do to ensure the data from the wide open throttle test is as precise as. This engine-side water separator is your last line of defense before water gets into your engine. Keep an eye on it and empty out any water that accumulates in the bottom.

Besides your engine not running or running poorly a periodic visual check of the fuel water separator on you engine is the best way to see if water is beginning to. The freshwater will leak out into the raw-water side and escape. To check for this type of leakage remove end covers from heat exchanger and drain raw-water.

Most antifreeze solutions have a color to them and are easy to see if they leak out into the raw-water part of the heat exchanger. Any engine thats fresh-water-cooled has a closed loop of coolant that removes heat and is in turn cooled by raw water pulled from the surrounding environment and passed though a heat exchanger. Unlike the coolant in your car which must be able to contend with below-freezing temperatures the primary job of the coolant in your boat is to.

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.
