Product Review: Keenan Filter Commander

Ever had your engine crap out at the worst possible moment?

Of course you have. Happens to all of us sooner or later. You’re motorsailing through a tight cut, current ripping, sails slack, and bam—engine coughs, then dies like it just remembered it’s unionized. Now you’re drifting, swearing, and diving headfirst into a furnace-hot engine room to figure out which cursed part of your fuel system decided to mutiny this time.

Been there. Done that. Don’t ever want to do it again.

That’s where Keenan Fuel Management Systems come in. These things aren’t just filters. Hell no. They’re like having a diesel-savvy old salt riding shotgun inside your fuel system—watching, analyzing, tweaking, and stepping in before stuff goes sideways.

Let me tell you a little story…

We were running down the Thorny Path, punching into trades like a drunken linebacker. One reef in the main, no wind in the genoa, and the iron genny doing all the heavy lifting. We’d just topped off fuel in the DR—dodgy stuff from plastic jugs at a dock that looked like it was held together with zip ties and wishful thinking.

Thirty miles offshore, halfway to Puerto Rico, the engine burps. Then sputters. Then flat-out dies. Just like that.

I go full monkey mode—dives into the engine room, boat rocking, sweat pouring, diesel stink in my nose. It was a clogged filter. Again. Changed it in seas that would make a billy goat puke. Then had to bleed the system, hand-pump the fuel, and pray the starter had one more try in it.

That was the trip that convinced me there had to be a better way. That’s when I found Keenan.

Their systems are a whole different animal. Instead of waiting for the engine to quit, they’re constantly keeping an eye on your fuel—pressure, flow, air bubbles, you name it. And their latest beast, the CommandBOSS, lets you run the whole show from your helm. I mean it—flip filters, polish fuel, move it from tank to tank, even spot trouble before it ruins your day. It’s like Mission Control for your diesel.

Here’s what you can do without ever leaving the wheel:

And yeah, it’s tailor-made for catamarans. The CommandBOSS control panel mounts right in your bridge, so you’re in command without crawling through hatches or contorting like a circus act. Sailors with monohulls? It still works beautifully—just maybe without the big helm layout cats get.

The CPRC-60 Cat Package is loaded and ready to rock:

Look—boats break. That’s part of the fun. But your fuel system doesn’t have to be the weakest link anymore. With a Keenan system on board, you’re not just avoiding problems. You’re outsmarting them.

You didn’t go cruising to become a diesel mechanic.

You went for the sunsets, the freedom, and the rum drinks at anchor—not to spend your days sweating in an engine bay with a wrench in your teeth.

Let Keenan handle the grunt work. You handle the sailing.
