Common Marine Engine Problems

What Happens When Water Gets Into a Diesel Engine?

Marine diesel engines spend their operating hours in the water, so water damage is a big concern for boat and yacht owners. So, what exactly happens when water gets into a marine diesel engine? If you get water in your yacht engine, don’t panic. Water may find its way into your cylinders, but it can often be removed by professionals who know how to decompress waterlogged areas of your engine. Some engines with water-cooled systems may need a cooling system flush if they’re not operating properly.

Trying to run a waterlogged diesel engine can result in hydrolock, a problem that can be costly to fix.

Marine Diesel Engine Troubleshooting – The Fix May Be in the Filters

Your yacht or boat’s engine relies on clean fuel that’s clean down to the microns. This means that a damaged or old filter can put your entire engine at risk, allowing dirt and water to enter your diesel engine and wreak havoc. One of the simplest marine diesel engine troubleshooting tips is to switch out your filters for new ones.
