Hello, John Talley here with boats.net. Today we're going to spend a little bit of
time discussing where you can find the pertinent information on your propeller when it comes time
to replace it. Now I want to go ahead and tell you it's best to find this information when the prop
is brand new. That way it's easier to read it, and then you need to write it down
and put it away somewhere safe when it does come time to replace that prop.
Each one has their own location, and sometimes information that's available.
What we're going to do is go through each, where I can explain the best places to look for it and
then what the information actually means when you see those magical numbers and letters.
So let's take a look at this Honda prop right in the middle. Now this is an aluminum one,
and typically on your aluminum props they're going to be stamped and/or engraved. On this particular
one, they've got a set of numbers on the side of it and it's 9.25 times eight-- or that's by eight.
Now what that's telling me that this is a nine and a quarter inch diameter prop
with an eight inch pitch. It's got another set of numbers
on here 1420. Now I would imagine those are some type of internal reference that Honda--
maybe even a batch number that Honda came up with when they produced this prop.
Other than that, it just has the Honda logo on the side.
Next let's switch over to an Evinrude-Johnson. It's another aluminum prop, nothing on the inside.
Outside? Set of numbers on the outside, but I’m betting 2820 has nothing to do with the
pitch or the diameter. That's another internal number that they are using.
Ah, but look at this one: 7-7-8-8-6-3. Now I would bet that is the specific part
number for this particular prop. Let's keep looking.
10.3 x 13.
Now unlike Honda they just went the 10.3. I guess they rounded up for that quarter inch, because I
know with this particular part number this is actually a 10 and a quarter inch diameter prop.
So let's take a look at one of the stainless Solas props. Now they elected to put their
information on the outer part of the hub, and there's no mistaking the manufacturer
of this nice big, bold, and easy to read. Now what they've done is they've incorporated both
the actual dimension information as well as the specific model number all in one number.
The 1-4-3, one that designates part of the part number for this particular one.
Next you're going to see 13.3 and then 17. Now those two numbers represent the dimensions
like we saw on the previous two props. 1-3-3, that's going to be 13.3 or 13.25,
and that's going to be your diameter. Next is the 17 and that's going to be your pitch.
Now in this example it's the same scenario as the first Solas that we looked at. Once again,
the first four numbers 9531 has nothing to do with the dimensions. That is strictly a part number.
The rest of it, 145-15, that's a 14.5 inch diameter 15-inch pitch.
Now let's switch over and take a look at one from Quicksilver, or Mercury Marine.
All right they actually stamp it, or cast it into the outer part of the hub. But if
you're looking at that the way I am, that is a little bit difficult to see.
But just to make sure that you're able to get this information, they actually
cast it into the inner part of the hub as well and that's a whole lot easier to read. However,
when this prop is installed those numbers are going to get covered up by the washer as well
as the bolt that holds the hub in place. Let's take a look at another one from
Mercury Marine. And this is a stainless one, and notice that they’ve got it laser etched on the
side. But I guarantee that's going to wear very quickly even though this is a stainless product.
Now if you look down in the center, they have all that information stamped onto the hub itself.
Trick is, you'd have to pull it to probably see it so reading that one-- RQ4, which is the series--
14.6 by 21P. There you go. Very straightforward. Next let's take a look at the Suzuki, and like
Solas they actually engrave it on the outside of the hub as well. The difference with this
system is they do not use a part number. It is strictly the dimensions of what you're looking at:
3X, which stands for three blade; 16, which is your diameter; and then 20,
which is your pitch. But look, they added one more letter to that. R, that refers to the rotation,
standard right hand rotation for this prop. Next, let's take a peek at this Yamaha one.
Nothing on the inside, nothing on the outside of the hub.
Where did they put the number? All the way on the back side of the inside of
the hub is where you're going to find this one. Yamaha tends to hide theirs away. The
only way you can find this information is to actually remove it off of the drive itself.
All right guys, there you go. Several examples of where you need to look to get the information
on your prop. And I do want to stress the most important part is to go ahead and do
this early when the prop is new and these numbers aren't worn away or hard to get to.
That way, when it comes time to replace your prop, you already have your information ready to go.
