OSO-Clean
Whether you cruise often or just a few weeks a year, clean fuel is a necessity. A rough sea can wreak havoc with your diesel fuel, stirring up months of muck from the bottom of your fuel tank clogging fuel lines and ordinary filters. Suddenly, in the midst of a squall, with wind and sea rising, your engine conks out. You head for the hot, cramped engine room, now rolling from side to side, to change the filters. It’s never fun and may result in costly towing charges and even damage or injury to you or your crew.
When you finally make it to the dock, you call the local fuel polishing service and spend a few boat bucks having your tanks cleaned and your filters overhauled.
No matter how often you use your boat, when diesel fuel sits in your tank, especially in Florida’s hot, humid environment, water will form and algae will die and fall to the bottom of your tank, creating muck and sludge that - given a little “confused sea” - will end up in your fuel lines.
So, we decided to develop an on-board system to clean fuel continuously. Our research showed that most on-board fuel polishing systems simply use the same types of filters already used on most boats with a low capacity pump and a spring wound timer. We knew there had to be a better way to provide continuous, unattended fuel polishing.
JTB Marine has developed OSO-Clean, a compact on-board fuel purification system designed to fit sail and power boats of 32’ or larger. The smallest model of our unique combination of filtration, pumps and timing mechanisms fits in a space as small as 12” x 18” and is quick and easy to install.
Our exclusive RCI fuel filters never need maintenance or cleaning, eliminating bulky filter storage and that yucky mess. Our custom combination of filter and pump sizes adapts to fuel tank capacity ranging from 50 to 10,000 gallons.
