Can you flush an outboard while in the water?
Outboards used in brackish water, or in freshwater that’s silty or muddy, should also be flushed. Flushing is usually an easy procedure, and can often be accomplished with the boat on a trailer or in the water at a dock or mooring.
Do outboard motors need to be flushed?
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.
How long do you flush 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.
How long can you run a boat motor on muffs?
Don’t run the engine unattended. Keep an eye on the muffs and make sure they don’t slip off of the water intakes. Regardless of your task, it’s unlikely that you’ll need to run it more than 10 to 15 minutes.
What happens if you don’t flush your boat 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.
