Prop for Yamaha F70

Does your stock prop need a replacement? Well, good riddance. You need a change for sure. Sure, Yamaha makes great props for their engines.

But we know how expensive the OEM parts tend to get.

So we thought about making a list. And here we are. If you’re in the category of buying a new prop for your Yamaha F70 engine, you’re in luck.

We had the privilege of going through twenty different propellers and picked the top five.

So, if you’re going through the list, you might find the best prop for Yamaha F70 for you. The engine is a 70hp beauty, so a good prop only compliments it.

I mean, we didn’t stop there. We even added some tips that will help you make the purchase decision when you’re choosing. So, what are you waiting for? Let’s get on with it.

Our Top Picks

1. OEM Yamaha Aluminum Prop

OEM Yamaha Aluminum Prop

Well, we tried not to put an OEM part on top of the list. That’s because they tend to be super expensive at times.

But we had to put this one on the list because it just provided enough value. It’s no surprise that this one is an expensive start, so it’s also got a lot to prove.

When you’re thinking about Yamaha, you might have a lot of industries spinning in your head.

But you know how they make good stuff for their boat engines. And this one impressed us enough to put it on top.

Let’s think from your perspective. You’re probably looking for a one-to-one replacement for your stock prop.

That’s probably because the ends got chipped or something.

Well, if you have the cash to splash, this is a no-brainer. Choose this one. We won’t stop you.

But things can get a bit more interesting than this.

I mean, it’s an OEM replacement, how can it go wrong, right? Well, there are a couple of ways for it to go wrong. But we’ll get to it in a bit.

Let’s talk about how we installed it. Well, it was a simple pop-in pop-out situation here. Okay, maybe it was a bit more complex than that, but you get what I mean.

We were able to replace the prop without any professional help, so that’s a plus. But since we were testing out loads of different props, we became something close to professionals too.

Jokes apart, we didn’t have much trouble with the installation.

Yamaha might offer excellent compatibility, but let’s stick to the Yamaha F70 engine for now. That’s a fantastic engine, and it requires a sweet prop.

We were able to test this one out in the open waters for around three weeks. The prop managed to last all three weeks without any visible dents on the blades. That’s awesome, right?

I mean, we were pretty mean to it during the testing process. And we didn’t fail to push any one of these to the limits. I just hope the boat we borrowed to test this out sees better days.

So even though it’s an aluminum-bladed prop, it held up quite well. And, I think it’s fair to say that aluminum is slowly but surely winning the market over.

It’s not all good news, though. I mean, of course, the first complaint is that this is expensive. You will get other props that perform close to this one. I mean, they may not go toe-to-toe with this OEM one, but they’re up there.

We’ll shed more light on them in a bit. But the price is a major concern for this one. Another problem that we faced was with vibrations. I mean, it wasn’t too high, but I didn’t think the OEM prop should have vibration issues.

  • Built decently
  • Blades accelerate well
  • All three blades are decently lined up to cut water
  • Doesn’t struggle with higher RPMs
  • Simple installation process
  • A bit on the pricier side
  • You might face some vibration issues


2. Qiclear Marine Aluminum Outboard Propeller

Qiclear Marine Aluminum Outboard Propeller

Up next, we have this one from Qiclear. You might never have heard about them, but we chose this for a couple of different reasons. It even gave some tough competition to the Yamaha OEM one on top that we reviewed previously.

Well, let’s get this out of the way first. The white color grew on me for some reason. But it’s just another plain white prop with three blades.

Oh, this one’s made with aluminum blades too. You might go and say that aluminum isn’t going to last long. I do not deny that, but during our testing, it felt right.

The three blades make the entire prop decently efficient. So you don’t have to worry about vibrations, or so we thought. There was actually a bit of vibration on it. But it wasn’t anything groundbreaking.

We needed to tinker with it during the installation. At one point, one of us, even though this wasn’t going to fit. But it did, after a bit of tinkering, that is.

They boast a lot about zero compromises with the higher RPMs. But our testing said otherwise. I mean, the results weren’t bad. But you have to understand that we’re looking for above-average performance, and false claims aren’t a good example.

The prop does struggle during the higher RPMs. We tested this out for around three weeks. The durability is decent. We didn’t observe any bends or dents during the testing phase. But it was only three weeks, so we’re not guaranteeing anything.

If you’re concerned about the performance, well, during the mid RPM levels, this prop hit the waves just right. We were getting crazy numbers by riding the boat out in the ocean. But after a few revs and pushing it to the higher RPMs, we saw a bit of a performance dip.

The word we were looking for was “satisfactory.” And the performance is just that. It’s not unique, and it has its flaws.

But we still placed it in a comparatively higher spot on the list, right? So, there’s more to it.

Firstly, the pricing made it a convincing choice. Don’t get me wrong. It isn’t the cheapest prop on the list for your Yamaha F70 engine. But if you compare it with the OEM models, it’s a decent bargain.

Since it’s not made of stainless steel, the blades might suffer upon collision with larger rocks underwater. So, be aware of those annoying rocks if you’re driving a boat with this prop on. I mean, hitting a boulder with a steel prop would’ve done some considerable damage, too, right?

  • Decent build quality
  • Good acceleration in the ocean
  • Great balance most of the time
  • The aluminum blades spin smoothly
  • Great value for money
  • Might struggle with higher RPMs
  • Installation is not very easy


3. VIF Jason Marine Aluminum Propeller

VIF Jason Marine Aluminum Propeller

Coming in at third place is this one from VIF. This one is so similar to the second one that we were often confused about which one was which. Differentiating between them was also a hassle. But we ended up with a verdict, as you see.

They claim that the prop is a one-to-one fit with the OEM one. But we had a little trouble trying to get this one onto the engine. So we had to take help from a couple of experienced professionals. Yeah, our techniques didn’t cut it this time.

I mean, this one is decent as a replacement prop. It’s not the outstanding prop as they advertise. This one comes with a couple of flaws, and we’ll get there.

But for the price, I mean, can you really complain? Most people will choose a prop based on the price, of course. And if they see a good review, they might not think of anything else. That’s what has been going on for so long.

As for durability, it was decent. I mean, since we didn’t hit any boulders during our two weeks of testing, we expected as much. There was a bit of jittering when we pushed the engine further. But I wouldn’t complain.

However, we did see a slight bend that wasn’t there when we unboxed it. So something surely happened. We couldn’t get to the bottom of this, sadly. That’s a shame.

I wonder whether a shark said “hello” to the prop when we were riding or whether one of our employees dropped it. Well, guess we’ll never know.

And, you might not complain either. Most people fall for the cheaper product even if they can live up to half of their expectations. And this one should exceed those expectations. So why not?

The fit is decent, the pricing is excellent, and the build is nice. So what’s wrong? Well, you might have trouble during the installation. And, there’s also the chance of sudden vibrations when you rev the engine far enough.

  • Good value for money
  • Smooth during medium speeds
  • The blades spin evenly on the water
  • Blade acceleration is decent
  • Good compatibility
  • Installation is a bit tricky
  • The aluminum isn’t the best quality


4. OEM Yamaha Prop

OEM Yamaha Prop

We’re closing towards the end of the list. But we’re not done yet. In fact, we have another OEM prop here at fourth. Well, if you’re wondering how an OEM part is so far down, read on to find out.

It’s the same three-blade design as all the other ones on the list. We’ll talk in detail about this in the next part, but you should know this. Right now, until any fancier technology comes out, three blades are the meta. And you can hit that sweet spot for efficiency with the three-blade design.

The build quality seemed excellent on this one. We expected as such. Strong aluminum is getting the job done now, so you shouldn’t be too concerned, or so we thought.

Well, I won’t blame Yamaha for this. I think this was a mistake on our part. We ended up testing this one for around ten days. Because on the last day of testing, we hit something underwater.

One of us jumped in to find out what the matter was. And it was just as we expected. The prop collided with a huge boulder. We even had a complete rescue mission too. But let’s leave that for another day.

So, what was the result? Not anything too dramatic, just a broken blade. But we know that the collision was hard, and we were lucky none of us got hurt. So, we’re not blaming the build quality and durability of the prop.

We’re just stating the fact that hitting a boulder accidentally might have a higher chance of causing you damage than you think. So ride carefully because we clearly weren’t.

As for the performance before the incident, well, we had a blast with this one. It might have even made it further up the table if it wasn’t for the awkward pricing.

It’s crazy how expensive these OEM parts can get. We side with the consumers in this case. It’s not like they’re selling us an airplane propeller, right?

The performance was satisfactory. We didn’t have to overthink since the blades spun smoothly throughout the testing.

Don’t worry. We pushed the engine to its maximum extent to see how this one would be fair. Well, it didn’t struggle in the higher RPMs and cut the water just fine. Props to Yamaha for that.

  • The blades spin smoothly
  • Decent acceleration on the blades
  • Deals with the higher RPMs quite well
  • Easy installation
  • Balance overall performance
  • A bit on the pricier side
  • Build quality could’ve been better


5. POLASTORM Aluminum Outboard Prop

POLASTORM Aluminum Outboard Prop

Finally, we’re ending the list with a prop from POLASTORM. Don’t skip this one just because it’s at the bottom of the list. Remember that this also had to survive the competition to get here.

Just like all the other props on the list, this one has three blades too. It’s another aluminum prop too. But this one held up quite well when we put it to the test.

There’s not a whole lot to it, except the fact that it’s a decent choice. We honestly can’t fault it too much since it’s already gotten a punishment by being placed on the last spot.

But there were a couple of concerning moments that we thought about. We tried to install it ourselves and did so. But we weren’t getting optimized performance from the prop. So we had to take it to the experts.

They had to make a couple of adjustments and then reinstalled it. So we’re just saying that you might need to do that too.

When it comes to the build quality, we didn’t see any notable dents or bumps. So our three-week testing phase was a success.

Honestly, we were just happy that the consumers had an affordable option for their beautiful Yamaha F70 engine. It’s no slacker. I mean, okay, it struggles with the higher RPMs. And it was pretty noticeable.

But that’s common among the best of the bests too. So let’s not nitpick.

When it comes to acceleration, the blades felt just fine. I think it’s a pretty decent choice for the budget. You may have another opinion. We’re not saying that this is the best prop out there. So take your pick wisely.

  • Decent build quality
  • Affordable choice
  • Moderately simple to install
  • Performs well in most conditions
  • Decent acceleration on the blades through water
  • Might feel sluggish during the start
  • You might need a couple of adjustments


Buying Guide

Now that we’re done with the different reviews of the props, it’s time for you to go out and make a purchase, right? Well, not really. You’re supposed to consider a few factors first. Now, we’ll talk about those.

Is Steel Better?

The material is the first thing you should consider when looking for a good propeller for your Yamaha engine. Now, propeller materials make a huge difference if you’re not aware already.

If you’re wondering what the most common two materials there are, well, they are steel and aluminum. To be more precise, it’s stainless steel that we’re talking about.

And both types of materials have their pros and cons. Aluminum propellers have come a long way from where they were ten years ago. Some might disagree, and that’s completely fine.

That’s because the top-quality stainless steel props are still untouchable. Some would go as far and say that the stainless steel ones would last you for decades. Well, we’re not going that far.

Aluminum blades are getting better and better. And we have the counterargument that aluminum is the future. But there is still a concern, though.

If your engine’s prop hits a rock underwater, you might want the prop to be a steel one instead of an aluminum one. But there’s also the incredibly low possibility of hitting a rock with your propeller when you’re in control.

Think About Where the Cup Is

newer guys looking to buy a prop

If you’re already aware of this, you can skip this. But for the newer guys looking to buy a prop, let’s talk. Typically, you will see two types of props based on the placement of the cup.

This cupping is either seen at the tip or towards the tip of the blades. And in other cases, the cupping is located along the trailing edges of the blades.

Now, the locations of the cups make sense. And you can’t undermine one and favor the other. So what’s the difference?

If you’re looking for a bit more increased bow lift, then it’s helpful if the cup is towards the tip of the blades. And if you want to have the ability to increase the pitch size, then the latter might work very well for you.

How Many Blades Do You Need?

It’s a common question for all enthusiasts. And many people debate on online forums about the number of blades. We won’t give you any more eyesore.

The straightforward answer is that fewer blades are better. But there’s a limit to how low you can go. You can’t move forward in the water if you’ve got a prop with one blade.

I don’t think they even make propellers like that. I digress. Three propeller blades should be the standard. Not more, not less. I mean, you can go for more, but they have certain drawbacks too. We’re getting to it.

If you want your propeller to be the most efficient, it’s best to have fewer blades. I mean, three blades are the sweet spot. If you go with two blades, you get to witness some funky vibration. And I don’t think you would have appreciated that.

How Many Blades Do You Need


When you are making your purchase decision for a propeller for your Yamaha F70 boat engine, it is important to take into account the propeller’s diameter.

Propellers with a larger diameter will provide more power and efficiency than those with a smaller diameter.

However, it is important to remember that a larger propeller will also be heavier and require more torque to operate.

Build Material

When looking to buy a propeller for the Yamaha F70 boat engine, it is important to consider the build material. The Yamaha F70 boat engine uses a steel shaft and aluminum fin blade.

Because these materials are not as durable as other types of propellers, it is important to choose a propeller made from a durable material. Some good options include metal-alloy or composite propellers.


Do I need to change the pitch?

You might need to change the pitch depending on whether you’re over-revving or under-revving. A professional mechanic can help you out with this.

Why is my boat sluggish?

If your prop is ventilating a bit too much, the issue would be with the propeller. Changing it might be a wise decision.

Is a four-blade propeller bad for my boat?

It’s not bad. But you will lose out on efficiency. You might get a bit more control, but I don’t think that’s worth it.

What prop comes on Yamaha F70?

The Yamaha F70 comes with a 3-bladed fan that can be controlled by the rider using a switch on the left handlebar. The PowerTech SRD3 is pre-set at 7 levels of speed and has three settings: low, medium, and high. The Yamaha F70 also includes a digital display that shows the rider’s current speed, battery level, and time.


That’s it from us. All the props on the list have a certain uniqueness. We think we got enough details through to you. Our extensive reviews should pass along the key points to you, helping you with the purchase decision.

Now, listen, you’re the one responsible for picking the best prop for Yamaha F70 for you. We’re not even trying to influence you. Our job is to enlighten you with some points you might not find everywhere. But the ultimate decision is yours to take.

But if you compare the features and the prices, you will obviously get a better understanding. In this way, your purchase won’t be affected by the clouded judgment. And your boat will have a good time too.

So ride the waves carefully and don’t forget to stay safe.
