DIY Yamaha 150 trim tilt motor replacement steps
Getting prepared to get a yamaha 150 trim tilt motor replacement isn't precisely how most boaters want to spend a Saturday morning, yet it's one associated with those jobs that eventually catches plan everyone. You're in the boat ramp, you hit the in order to drop the motor into the drinking water, and instead of that familiar hydraulic hum, you obtain a clicking on sound or, actually worse, total silence. It's frustrating, sure, but the great news is that you simply don't necessarily need to bring your boat in order to a mechanic and drop a thousands of dollars to get it fixed.
If you've obtained some basic equipment and a little bit of persistence, you can change out that damaged motor yourself. These types of units live in a pretty harsh atmosphere, especially if you're running in saltwater, so it's no real surprise they eventually quit the ghost. Let's stroll through how to handle this particular without losing your mind.
Spotting the signs of a dying motor
Before you go tearing things apart, a person want to become sure it's in fact the motor that's the problem. Sometimes it's just the blown fuse or even a bad relay. If you hear a "click-click" from the engine cowling once you hit the trim button, your relays are probably good, as well as the power is definitely trying to get to the motor, but the motor just can't switch.
Another useless giveaway is if the particular motor works intermittently. If you have to tap the particular motor housing along with a screwdriver deal with to get this to move, the inner brushes are most likely worn out or trapped due to deterioration. When this occurs, a yamaha 150 trim tilt motor replacement can be quite much inevitable. You can try to clean them, but truthfully, once the seals fail and dampness gets inside that will little electric motor, it's a ticking time bomb. It's better to simply swap it out there and also have the serenity of mind.
Getting your tools and parts collectively
You don't need a massive workshop for this, but a person do need the particular right stuff. Most Yamaha 150s use a three-wire or two-wire setup depending on the year, so make sure you've ordered the specific replacement that fits your model.
For equipment, grab a collection of sockets (usually 10mm and 8mm), a flathead electric screwdriver, and some needle-nose pliers. You'll also want a can associated with high-quality penetrating oil like PB Blaster or WD-40 Specialist. These bolts spend their lives immersed in water, therefore they're probably going to be stubborn.
Pro tip: Get the tub of marine-grade grease. You'll need to coat the new bolts and the O-ring during the particular install to create sure things remain sealed and don't seize up with regard to the next guy (who might be you in five years).
Step 1: Safety very first and manual discharge
First items first, you possess to get the engine tilted all the way upward. If your motor is completely dead and the engine is usually stuck in the "down" position, you'll want to use the particular manual release control device. It's usually a large flathead mess located on the particular side of the particular bracket. Provide a few turns counter-clockwise (don't take it all the way out! ), and you ought to be capable to manually lift the engine.
Once it's upward, indulge the tilt lock lever . In no way, ever work on the trim program without that mechanical secure place. A person don't want 480 pounds of Yamaha outboard crushing your fingers if the hydraulic seal chooses to let go while you're working.
Step 2: Getting rid of the old motor
Now arrives the fun part—or the annoying part, depending on how much rust you're working with. The trim motor is held onto the a lot more by several lengthy bolts. On the particular Yamaha 150, these are often 8mm or 10mm.
Before you decide to actually touch associated with the wrench, soak them in penetrating oil. Let it sit down for ten or fifteen minutes. When they feel like they're going to snap, give them just a little heat or another bathe. If you click a bolt mind off in the trim manifold, this "simple" DIY job just turned into the nightmare involving extractors and drill parts.
Once the particular bolts are out, you'll need to disconnect the wires. Follow the wires up into the particular engine cowling. You'll usually find them plugged into the relay junction. Disconnect them and draw the harness through the rigging grommet.
Step a few: Prepping the mating surface
With the old motor off, you'll notice the internal push shaft or "coupler" that connects the particular motor to the pump. Take the rag and clear that whole area. You don't would like any dirt, sodium, or old crusty oil getting straight into the pump assembly.
Check out the O-ring. Nearly all new yamaha 150 trim tilt motor replacement kits come with the new O-ring. Make use of it. Set up outdated one looks alright, it's not worth the risk of a leak. Smear just a little marine grease within the new O-ring to help it seat properly and produce a solid close off against the casing.
Step 4: Installing the newest motor
Slide the new motor straight into place. You may have to shake it a bit in order to get the shaft to line up with the push. Don't force it—it should seat remove against the a lot more quite easily once the particular splines line up.
When you place the bolts back in, coat the threads with grease or even anti-seize. This is definitely a gift for your future self. Tighten them down in a criss-cross pattern to make sure even pressure for the O-ring. You don't need to move crazy with rpm here; bad them "snug along with a small bit. "
Step 5: Routing the wiring
Feed the fresh wiring harness back again up through the same path the a single took. Make sure you use the rubber grommets to prevent the wires from chafing contrary to the metal brackets. Plug everything back again into the exchange.
In the event that you bought an aftermarket motor, sometimes the wire shades don't perfectly match up the factory Yamaha colors. Usually, it's green to green and blue to blue (Green regarding "Grass/Down, " Azure for "Sky/Up"), yet always double-check the tiny instruction sheet that will comes in the box.
Bleeding the environment out there of the program
Once everything is bolted up and plugged within, don't just drop the boat within the water. You've likely introduced a little air into the particular system, or from the very least, you need to make certain the fluid levels are right.
- Close the manual release device tightly.
- Turn the tilt lock lever up plus use the switch to run the motor.
- Run everything the way up and everything the way straight down four to five times.
- If this sounds "girgly" or moves jumpily, there's air in there.
- With the motor in the full "up" position, open the fluid water tank cap (the huge plastic or metallic plug on the particular front of the particular ram).
- Top it away from with Dextron III ATF or particular Yamaha trim fluid until it begins to spill away.
- Put the cap back upon and cycle it again.
Eventually, the air flow will work the way out, and the motor can sound smooth plus consistent.
Is definitely it worth performing it yourself?
I believe, absolutely. A shop is going to charge you for a minimum of 2 to three hrs of labor, plus they'll likely mark up the price of the motor itself. If you purchase an established aftermarket motor, you can finish the yamaha 150 trim tilt motor replacement for the fraction of the particular cost of a dealer repair.
The particular only real "danger" is those stuck bolts. If you live in a place where the boat stays in the particular salt all yr, those bolts may practically become a single using the bracket. But if you consider your time, use lots of lubricant, and don't try to "gorilla" the wrench, it's a very workable project.
As soon as you're done, give the whole region a good aerosol using a corrosion inhibitor like Fluid Movie or Yamashield. It'll keep the new motor looking fresh and help prevent that salt crust from forming again so soon. Now, get that boat off the particular trailer and back into the drinking water where it is supposed to be!
