Turbo® propellers are part of Yamaha’s
“Endless Propeller Solutions”. When
testing boats for Performance
Bulletins, we at times find that a
Turbo propeller is the best choice
for a particular boat package. When
that occurs, we’ll list it right on
the Yamaha Performance Bulletin;
including the family name, style, and
part number; the same as we do for
all other Yamaha propellers. As usual,
we’ll also list the actual conditions
under which that data was collected,
along with performance data such as
speed, fuel burn, engine rpm data, etc.
You can find Yamaha Performance
Bulletins on our website at
yamahaoutboards.com.
As a general rule, the correct propeller will allow your engine to reach
the upper portion of the WOT (wide open throttle) range specified by
the manufacturer without exceeding it, with a normal-to-heavy load.
For example, if your outboard says WOT is 5000-6000 rpm,
you need a prop that will allow your engine to turn between
approximately 5700 and 6000 rpm with your average load in the
boat. Be sure to account for things such as fuel, full bait and/or
live wells, batteries, passengers, and all gear, including safety gear
(anchors, ropes, fire extinguishers, etc.)

1 | To begin, check Yamaha’s Performance Bulletins on our website
at yamahaoutboards.com. Choose the type of boat most
similar to yours (or the one you want), and note what propeller
is listed.
2 | Next, check out the propeller solutions applicable to your
particular horsepower Yamaha outboard in our propeller charts
located at the bottom of our marine website’s landing page (there’s
other great propeller information in here, too). Look for the same
series name and pitch of propeller as the Performance Bulletin, then
adjust the pitch depending on weight and altitude (heavier weight
or higher altitude, pitch down…light or low, pitch even or slightly
up). Each inch of propeller pitch is equal to approximately
100 +/- 50 rpm.

“The latest news about Yamaha propellers”
VOL. 1 | EDITION 2 | AUGUST 2011
Endless Propeller
Solutions by Yamaha
keeps moving forward
In the last edition, we introduced you
to Yamaha’s guiding philosophy regarding propellers. It’s all about propeller
solutions, to meet a wide array of
marine applications, and Yamaha
offers them in more ways than you
most likely know.
In short, with all that Yamaha has
to offer in regard to propellers,
virtually any boat can perform at
its peak. How? Of course we offer
propeller solutions that make Yamaha
outboards perform. But we also offer
the same or very similar performance
for nearly any outboard manufacturer.
We even have some for sterndrives.
That most likely means Yamaha has
the right prop to fit your boat, too,
regardless of type or application.
And our ability to do so keeps growing.
Endless Propeller Solutions by
Yamaha. Well beyond expectations.

of the month
Endless Propeller Solutions by Yamaha
expands…again!
The depth and breadth of Yamaha’s alreadycomprehensive propeller solutions keeps growing.
Precision Propeller Industries, Inc. has launched the new high-performance FXP
propeller from Turbo®. Engineered to deliver outstanding overall performance
at tournament load, it’s intended specifically for today’s high-performance,
high-output four-stroke bass boat outboards, like Yamaha’s V MAX SHO®.
It also works well with these type outboards in selected bay and flats boats
applications, and it perfectly augments Yamaha’s high-performance V MAX®
line of propellers in all of these applications.
The new Turbo® FXP delivers
outstanding results along all
measures of propeller performance
— hole shot, acceleration, top speed
and handling — rather than focus
on one or two performance
attributes as some competitor’s
props do. High performance four
stroke outboards have different
propeller needs than their
two-stroke predecessors, and
the FXP is the first propeller
specifically designed to address
all performance criteria in
applications using these
special outboards.
Designed to excel at tournament
loads, FXP propellers offer
near-custom out-of-the-box
performance by featuring 1”
pitches between 22” and 27”.

4 | Lastly, check our “Prop Shop” publications on our website for the
latest news on new propeller releases and even unusual propeller
applications we’ve uncovered (you’ll find a link in the propeller section
on our website). It might help you find just the right prop for your
needs. Make sure to check the archive of past issues, too – the
specific information you need might just be there.
5 | It goes without saying that on-water testing is always best,
as each application is different. That’s where your Yamaha dealer
comes in. They’ll be able to help you determine the prop that’s right
for you, and may even have the means necessary to test a few. You
can find Yamaha Marine dealers on our website. Give them a call
to discuss your particular situation. If you can, make sure to have
handy any of the above information you’ve recorded, such as: boat
make, model and year; engine model and primary identification
number; current prop size and style; current maximum rpm at wide
open throttle; and typical and maximum loads (weights) carried.

You’ve got propeller questions? We’ve got answers.
Our continuing series, aimed at demystifying the world of propellers. Portions are reprinted with permission from
Yamaha’s The Boater’s Log, Vol. 3, No. 14.
Q. My outboard exceeds the engine manufacturer’s recommended rpm at full throttle (or the engine hits
the rev limiter). Do you think the prop has anything to do with this?
A. More than likely, installing a propeller with a higher pitch number could help. Engine rpm should decrease about
150 +/- 50 rpm per inch of pitch with a higher pitch prop (of the same style). A propeller with more pitch should
bring the outboard’s rpm down to where they should be, improving the engine’s mid-range cruise economy, and
if you’re lucky, you could gain a little more top speed – maybe. Watch the outside air temperature when testing
your prop. There’s a big difference in performance between cool weather and hot weather. The swing can be as
much as 200-300 rpm from 55 degrees to 95 degrees.
Pitch
Pitch is the distance (in inches) a particular prop would theoretically
travel in one full revolution, as if traveling through a solid. A lower
pitch will have greater acceleration and pushing power but a lower top
speed, while a higher pitch prop will provide less acceleration, but a
greater potential for higher top speeds. The correct propeller will allow
your engine to reach the upper portion of the WOT range specified by
the manufacturer with a normal-to-heavy load (without exceeding it).
Each inch of pitch is equal to approximately 150 +/- 50 rpm.

Endless Propeller Solutions – Out and About.
Yamaha is taking the “Endless Propeller Solutions” message to the streets – literally!
Here are a couple shots of our mobile propeller truck, just recently wrapped with our new ”Endless Propeller
Solutions by Yamaha” messaging. It’s a self-sufficient
rolling R&D lab, complete with all the machinery necessary
to modify propellers right at the ramp. It also serves as
a mobile repair shop. Look for it at select upcoming
tournaments and events, and rest assured, whoever’s
driving it knows about propellers. Stop by and say hello!

When Choosing a Prop
- Keep It Simple!
The world of propellers has always
seemingly been shrouded in mystery,
and unnecessarily so. You sometimes
hear of propellers referred to as a black
art, which only serves to further this
mystique. In fact, many are fearful of
making a recommendation or a choice
about propellers, seeing the issue as too
complicated or too involved.
When choosing a propeller, the trick is
to keep it simple. In fact, part of the
“Endless Propeller Solutions by Yamaha”
(EPS) philosophy intentionally involves
prop selection, using a new process that’s
simple to understand and specifically
designed to help eliminate confusion.
Unusual application of the month.
What’s another unique advantage of Performance
Bulletins when it comes to props?
When our Application Engineers are doing the testing for Performance
Bulletins, they occasionally come across propeller applications that you
might not ordinarily consider but that provide awesome performance
nonetheless. When we find situations like this, we like to pass this
information along. Our latest find, which has been consistently proven
in testing since, involves pontoon boats.
Pontoon boats have become more performanceoriented, and even we were caught by surprise by the
number of tri-log pontoon boats coming equipped
from the factory with V MAX SHO® engines.
We’ve found many of these packages
perform at their best with (surprise!)
Saltwater Series II propellers. These props
have the larger diameter many pontoon
applications need, and are offered with our Shift Dampener
System (SDS™) to help greatly reduce shifting noise and vibration.
Sounds odd – but it works! Remember, just because a propeller family is
called “Saltwater” doesn’t necessarily mean it won’t work in freshwater
applications, and very well at that!
Need more info? You can find examples of this set up in our Performance
Bulletins on our website at yamahaoutboards.com.
The “EPS” method is application based,
rather than product based. So, instead
of having to decide amongst a wall full of
propellers, you first simply pick the type
of boat you have from four (4) major
categories (Large, Medium & Small,
Family & Watersports, and Bass/Bay/
Flats). That means the pool of props
you have to choose from is immediately
smaller because only a certain number of
our propeller solutions are applicable to
that particular style of boat. Drill down
a little further, and the list of possibilities
becomes even smaller.
We’ll feature more on this new method
of selecting propellers in our next edition
of “Prop Shop”. Don’t worry…we’ll walk
you right through it.
If you’d like more information about which Yamaha propeller is right
for your needs, contact your local authorized Yamaha Marine Dealer at
