In the event that you've spent whenever on the water using a classic outboard, you've probably experienced a run-in along with a power trim model 200 unit. These items were the absolute workhorses of their period, and honestly, these people still endure amazingly well in case you treat them with a little respect. It's among those parts that a person don't really believe about until you're trying to get the boat on the plane plus nothing happens, or worse, you're stuck with the engine tilted all the way up within the middle associated with a busy ramp.
The Model 200 was a basic piece for years, specifically on those old Mercury and Mariner engines. It symbolizes a time when things were built to be fixed, not just tossed in the trash and replaced with a plastic equal. Even now, with the fancy digital handles on new boats, there's something satisfying about the mechanical grunt of these types of older hydraulic techniques.
What is this point anyway?
Basically, the power trim model 200 is the muscles behind your motor's movement. It's a hydraulic system which allows you to change the angle of the engine whilst you're moving—that's the particular "trim" part—and raise the whole thing out of the water when you're finished the day—that's the "tilt. "
Inside that metal housing, you've got an engine, a pump, plus a reservoir regarding fluid. If you strike the turn on your own throttle, the motor spins the push, which pushes hydraulic fluid to the rams. It's a simple concept, but it needs to work under a lots of pressure. Imagine the particular force of the 150-horsepower engine pressing against the water; the particular trim system offers to hold that position perfectly without having slipping. If it's working right, a person don't even discover it. You just feel the boat degree out, the Rpm pick up, plus the ride obtain a whole lot smoother.
The classic "It won't move" problem
We've all been there. You obtain to the dock, you're ready in order to go, so you hit the button. Click. That's it. Just a lonesome little metallic click on. When a power trim model 200 starts acting up, it's usually pretty vocal regarding it.
That clicking sound is often the particular solenoid. It's the particular gatekeeper that transmits power from the particular battery to the particular trim motor. If the solenoid is usually shot, the engine never gets the juice it demands. It's a cheap repair, thankfully, but it's annoying in order to happens miles in the trailers.
Then there's the sound of the motor spinning, but the motor not moving. That's usually a sign that you're low on fluid or even there's air stuck in the lines. Since these products are decades aged at this point, the seals have a habit of having brittle. Once a seal fails, you'll start to see that telltale rainbow sheen on the water at the rear of your boat. That's hydraulic fluid avoiding, and it indicates your trim system is slowly losing the ability to do its job.
Bleeding the system
If you've topped off the liquid but things still feel "spongy" or the motor jerks when it's relocating, you've probably got air in presently there. Bleeding a power trim model 200 isn't precisely an enjoyable Saturday evening, but it's required. Usually, it entails cycling the engine up and lower a few times while the fill plug will be loose, letting the air bubbles function their way out. It's messy, and you'll probably end up with a few red fluid in your hands, but it's the only method to get that rock-solid hold back again.
The dreaded manual release
Every boater need to know in which the guide release valve is definitely on their power trim model 200 . It's usually a large flat-head screw quietly of the bracket. If your battery dies or the motor uses up out, you can turn that mess to allow the stress out of the system. This enables you to by hand lift the engine up so you can get this on the trailers. Just be careful—once you turn that mess, there's nothing holding the motor upward except your personal strength, and the ones outboards are heavier than they look.
Keeping the rust at bay
Since these devices live in the water—and often salt water—corrosion is the particular number one foe. The power trim model 200 was built challenging, but aluminum plus salt don't go along. Over time, the mounting bolts can seize up, or even the motor casing itself can start to pit and flake.
One of the best items you can do is stay on top of your sacrificial anodes. Those small chunks of zinc are designed to be "eaten" simply by corrosion so your own trim unit doesn't need to be. If a person let the anodes disappear, the salt will start searching for the next best thing, which is usually usually your expensive hydraulic parts. The quick spray along with some corrosion inhibitor after a day time on the water also goes a long way. It's a two-minute job that can save you a thousand-dollar headache down the road.
Is it well worth fixing?
This is the big question for owners of older motorboats. When your power trim model 200 finally provides up the ghost, perform you repair it or replace it?
When the issue is just the motor or the solenoid, it's a no-brainer. You can find substitute motors for the devices fairly easily, plus it's a job you can do in your driveway with some basic tools. Even a seal off kit isn't as well expensive when you have the particular patience to consider the particular rams apart.
However, if the primary manifold is cracked or the internal pump is shredded, you might end up being looking at a complete replacement. There are aftermarket units accessible today that are designed to bolt right into exactly the same spot as the particular old Model 200. They're often lighter in weight and much more efficient, even though they lack that will "vintage" look when you're doing the total restoration.
The thing is , these old models are incredibly long lasting. I've seen Model 200s that look like they've already been at the underside of the ocean for a 10 years, yet with the bit of fresh fluid and a new wiring harness, they fire right back up. They will don't make them like that anymore.
Wiring and electric quirks
The particular wiring on the power trim model 200 is pretty straightforward—usually a green wire and a blue cable. A good method to remember it really is "green for grass" (down) and "blue for sky" (up). If your trim works in one particular direction although not the other, it's more often than not a wiring problem or a bad switch at the particular helm.
Before you go ripping the pump apart, check your contacts. Corroded wires are the supply of about 90% of electrical problems on ships. A bit of sandpaper to clear the terminals plus some dielectric fat can solve problems that seem much more "expensive" than they are often.
Final thoughts around the Model 200
With the end of the day, the power trim model 200 is definitely a classic item of marine engineering. It's not flashy, and it doesn't have any apps or Bluetooth online connectivity, but it does precisely what it was created to do. It gives you manage over how your boat sits in the water, helping a person save fuel and stay comfortable whenever the chop picks up.
In case you own one, look after it. Keep a good eye on the particular fluid, replace the particular anodes, and don't ignore those weird clicking sounds. A little bit of proactive maintenance makes sure that the only issue you have to worry about on your own next trip will be whether or not the fish are usually biting. These units were built to last, and with a little love, there's no reason your own Model 200 won't keep pushing your boat through the water for another twenty years. It's just solid, reliable gear that will remind us why all of us fell in love with boating in the first location.
