If you've already been looking for a 55321 87j01 , you probably already know it's one of these small, unassuming parts that actually performs a massive function in keeping your motorboat from falling apart. It's funny how a single chunk of metal may be the distinction between a smooth ride and a pricey repair bill, yet that's the truth when you're coping with Suzuki outboards. This unique part is a trim tab anode, and if yours is starting to look like some sort of piece of wrecked gum, it's certainly time to change it out.
I've spent sufficient time around docks to see what happens when people disregard their anodes. This isn't pretty. Many folks call them "zincs, " also though many modern ones are in fact produced of aluminum or even magnesium depending upon where you're boating. For the Suzuki DF series, the 55321 87j01 is definitely a staple. It's designed to match a wide variety of mid-sized outboards, particularly the DF40 with the DF70 models. It sits right there within the reduce unit, doing two jobs at the same time: performing as a sacrificial lamb for rust and helping a person steer straight.
Exactly what does This Component Really do?
You might wonder why a manufacturer might design a part specifically to dissolve. It seems counterintuitive, right? But the 55321 87j01 will be a sacrificial anode. In the entire world of marine the field of biology and chemistry, saltwater is basically a giant battery. When a person put different types of metal (like your expensive stainless-steel prop and your own aluminum engine block) into that water, an electrical current begins flowing between them. This process, called galvanic corrosion, consumes away at the "weaker" metal.
Without that 55321 87j01 bolted on, the drinking water would start eating your lower unit or your propeller shaft. With the addition of this particular specific alloy tabs, you're giving the corrosion something simpler to snack on. The anode "sacrifices" by itself so your motor doesn't have to. If you see your trim tab searching pitted or crusty, don't worry—that indicates it's working. It's when it remains perfectly shiny after a season in the water that you ought to actually be concerned, because it means the particular corrosion is likely happening somewhere else.
The second work of this component will be the "trim tab" aspect. You'll see it offers a bit of a fin shape. By altering the angle associated with this fin, you can compensate for "prop walk, " which is that annoying tendency for the particular boat to pull in order to one side whenever you're at cruising speed. If a person find yourself constantly fighting the controls to stay directly, your 55321 87j01 might just need a small adjustment.
Understanding If It's Time for a Change
A good rule of browse I always follow is usually the "halfway guideline. " In case your 55321 87j01 will be about 50% gone, just replace it. Some people try out to squeeze every last bit of existence out of them, but by the time an anode is 70% blended, it loses its electrical "surface area" and isn't safeguarding your motor because effectively.
Usually, you'll need to check this particular every time you draw the boat out of the drinking water for a clean or at the particular end of every single season. If you're boating in especially salty or comfortable water, things happen faster. Warm sodium water is actually the turbocharger for deterioration. On the reverse side, if you're strictly a fresh water boater, you might get a couple of yrs out of a single 55321 87j01 , yet it's still worthy of a look throughout your annual oil change.
Obtaining the Right Match
The 55321 87j01 is usually pretty specific in order to the Suzuki selection. It's most generally located on the DF40, DF50, DF60, and DF70 four-stroke models. When you have an older two-stroke, you might use a different part number, so it's always worth double-checking your manual. Nevertheless, for the contemporary DF series, this is actually the go-to.
Something to keep within mind is the material. While the part number 55321 87j01 usually refers to the particular standard aluminum alloy version (which is usually great for sodium or brackish water), some aftermarket variations might vary. Aluminum anodes have mostly replaced the old-school pure zinc types simply because they last more and are much better for the atmosphere. Plus, they work in a broader range of drinking water types. If you're strictly in fresh water, some guys swear by magnesium, but intended for the majority of us, the standard Suzuki-spec part is definitely the way in order to go.
Exactly how to Swap It Out Yourself
The best component about the 55321 87j01 is that you simply don't need to be a certified auto mechanic to change it. It's an one-bolt job. Honestly, the particular hardest part is normally finding the right socket size plus making sure a person don't drop the particular bolt into the particular grass.
- Locate the bolt cover: At the top of the particular cavitation plate (the flat "wing" over your prop), there's usually a little plastic material plug. Pop that will out with a flathead screwdriver.
- Loosen the bolt: You'll need a socket with an extension to achieve down directly into that hole. Generally, it's a 10mm or 12mm bolt. Turn it counter-clockwise.
- Pay attention to the angle: Before a person pull the outdated 55321 87j01 off, look at exactly where the fin will be pointing. There are usually usually little hash marks on the motor housing. If your boat has been steering perfectly, you'll want to place the new a single back on the precise same angle.
- Clean the particular mating surface: This is the step nearly all people skip. For your anode to work, it requires a great "metal-on-metal" link with the motor. If there's a bunch of salt crust or old paint exactly where the anode sits, grab a wire brush and provide it a quick scrub.
- Install the brand new 1: Slip the new 55321 87j01 in to place, drop the particular bolt back in, and tighten this up. Don't over-tighten it to the stage associated with stripping the strings, but make certain it's snug.
Don't Your investment Color Rule
Right here is a professional tip that saves plenty of headaches: Never paint your anode. I've observed people get the little too excited with the anti-fouling bottom paint and cover their 55321 87j01 combined with the rest of the particular lower unit. In the event that you paint it, you've essentially protected it. The electric current won't be able to reach the metallic, and the anode won't dissolve. That seems like a good thing until a person realize the rust is currently eating your own expensive propeller or even your trim tilt assembly instead. Maintain that hunk of metal bare plus ugly so this can do its job.
Exactly why Quality Matters
You'll see a lots of "knock-off" versions of the 55321 87j01 online for 5 bucks less compared to the original Suzuki component. While I'm almost all for saving money, anodes are one particular area where I actually usually stick to OEM (Original Products Manufacturer) or very high-quality marine brands like Martyr.
The reason is the blend mix. To function correctly, the metal must be a quite specific purity. In the event that the "zinc" you purchased is actually just the cheap lead-filled casting from a random manufacturer, it might not offer the electrical defense your DF70 needs. When you think about that the new reduced unit can cost thousands of bucks, spending an extra few bucks upon a genuine 55321 87j01 seems like cheap insurance.
Wrapping Things Upward
It's simple to overlook the little stuff when you're worried about gas filters, spark attaches, and water pushes. But the 55321 87j01 is definitely really the unsung hero of the Suzuki outboard. It rests underwater, slowly disappearing, just so that you can appreciate your day on the lake or the particular ocean without worrying about your motor rotting away from the inside out.
So, next period you're doing a walk-around of your boat on the trailer, take a second to look up under the cavitation plate. If that little fin is looking a bit tough around the edges, do yourself a favor plus grab a substitute 55321 87j01 . It's a ten-minute fix that keeps your steering straight plus your motor's metal where it belongs—on the motor. Delighted boating, and stay safe out generally there on the water!
