Yamaha Possible Coverup of Propeller Guard Documents Exposed

Yamaha Prop Guard Statements

Yamaha Prop Guard Statements

In March 2012 Yamaha announced a new stainless steel propeller guard for outboards on flood rescue boats in the UK and made several statements about how great it was, how well it performed, and even how prop guards were necessary when people were in the water near the boat. About October we became aware of Yamaha’s new propeller guard. In mid October we began posting some materials about it and some of Yamaha’s own statements about their guard.

The boating industry has long defended itself in propeller injury court cases by claiming propeller guards don’t work. Among their objections, the industry claims guards create too much drag, reduce performance (top speed), effect the handling of the boat, are not durable enough, get bent into the propeller, and they create blunt trauma injuries when they strike people.

But Yamaha was making the exact opposite statements about their propeller guard. Yamaha said their guard worked great, minimized drag and performance reduction, improved handling, was strong and durable for use in shallow water, and guards were essential for operating rescue boats near people in the water.

Our mid October 2012 posts echoed several of Yamaha’s own comments.

By early November 2012, everything Yamaha ever said about the propeller guard AND all records of the guard’s existence vanished from their website. We made many attempts to contact Yamaha about why they pulled all of their materials about the propeller guard, but they will not respond. That leaves us to suspect Yamaha erased their statements to protect the boating industry’s long standing legal defense, “Guards don’t work”.

Among the many specific statements made and deleted by Yamaha about their propeller guard were: Read More →

Research Projects for Senior Design Classes, Masters Thesis Projects, Industrial Design & Other Researchers

Most college students in engineering and design take one or more design project classes, often a Senior Capstone Design Projects Class, in which they work individually or as teams to develop solutions to problems. We are trying to tap this resource and encourage students to consider selecting design projects related to propeller safety. More student design projects would help grow the body of knowledge available to the industry and to boaters. In addition to engineering and design students, we also welcome those from all fields and encourage them to consider projects in this area for their capstone classes. If you or others are interested in a college design class project or capstone project in propeller safety, propeller injury avoidance devices, or related fields, please view the projects listed below and contact us for additional assistance.

Boating Safety in Press Release Images : Open Bow Wakesurfing Boat

Brunswick / Mercury Marine / MerCruiser recently released their new Bravo Four S forward facing stern drive. As part of the media coverage they released a number of images for the press / media to use while covering the release.

We noticed several of Mercury’s press release images for the Bravo Four S drive were taken with a Chaparral wakesurfing boat. Chaparral’s own website and BoatTest.com identified it as Chaparral’s 23 foot Surf model.

Chaparral posts some images on their website that appear to be taken at the same time as Brunswick’s press images.

We will start with a photo from Chaparral’s website.

MerCruiser adds Bravo Four S forward facing drive

Brunswick’s Mercury MerCruiser announced a new Bravo Four S forward-facing drive 24 August 2020. The drive obviously targets Volvo Penta’s FWD drive’s success in the wake surfing market.

Mercury paired the drive’s introduction with a new control system called Smart Tow controls that aids in creating specific waves for wakesurfing, wakeboarding, and other tow sports. The digital controls coordinate ballast, surf tabs, and the drive’s settings in a single user interface.

The drive will be available from their 4.5 liter, 6.2 liter, and 8.2 liter formats with 250 to 430 horsepower per their Bravo Four brochure.

WSF / WSIA silent kill switch PSA

Kill Switch Lanyard on Wrist

Kill Switch Lanyard on Wrist – Image courtesy of U.S. Coast Guard

Water Sports Foundation, Inc. (WSF), a division of the Water Sports Industry Association (WSIA) created a Public Service Announcement (PSA) video encouraging boat operators to connect their kill switch lanyard. The video was created as part of a U.S. Coast Guard grant. While the video is shot in modern times and uses background music it seems a bit like an old silent movie in that no words are spoken.

WSF did a great job in using emotion to bring the point home to boat operators. It is nice to see the use of a silent message that really drives the point home and it does it quickly.

Congratulations and thanks to WSF for creating this safety video. We encourage others to share it as well.

Don’t forget to attach your lanyard!

Propeller Safety BARD help

A number of materials have been created as part of a package to assist boat builders in using the U.S. Coast Guard Boating Accident Report Database (BARD) to Post Sale (after sale) monitor their boats for being involved in accidents. The hope is that boat builders will use that information to improve the safety of their vessels. Gary Polson of PropellerSafety.com / Polson Enterprises authored these materials.

These materials are not professional advice. They are educational materials to stimulate discussion and encourage boat builders to develop their own processes to best use BARD for their specific situation.

BARD Training Videos for boat builders & others

Training videos / Tutorials on how to use the U.S. Coast Guard Boating Accident Report Database (BARD) produced by Gary Polson of PropellerSafety.com / Polson Enterprises.

We hope these videos encourage boating safety professionals and those developing boating safety related products to use the BARD database to better understand boating accidents and to optimize their boat accident prevention / mitigation efforts. Those efforts may be behavioral efforts (encourage wearing of life jackets), device based (develop new devices to prevent boat accidents like an automatic kill switch system that does not require use of a fob), or regulatory based (like require use of kill switches when underway in certain vessels).

We especially hope boat builders will take advantage of the opportunity the U.S. Coast Guard BARD database provides to monitor the safety of their boats post sale (after sale), then use the information they find to make their boats safer.

Post sale monitoring of product safety is sometimes called post sale surveillance or post market surveillance.

BARD

U.S. Coast Guard Boat Accident Report Database (BARD) search strategies and methods for boat builders are presented in a paper by Gary Polson of PropellerSafety.com / Polson Enterprises.

We produced a series of videos in an attempt to expose members of the boating industry to the BARD database. We particularly encourage boat builders to use BARD as a tool to monitor post sale accidents involving their boats and use that knowledge to improve the safety of their vessels. Some call this post market or post sale surveillance.

This paper describes methods used in the videos to identifying accidents involving a specific boat builder’s vessels in BARD. It also discusses how certain search methods compare with one another in terms of how much effort and skills they require and how successful those search methods might be. Read More →

Propeller Safety BARD help logo

The U.S. Coast Guard Boating Accident Report Database (BARD) should be a central component of boat builder / boat manufacturer efforts to monitor the safety of their boats post sale (after sale / in use by customers). Similarly, marine drive manufacturers can monitor BARD for potential safety issues involving marine drives.

Post Sale Monitoring is sometimes called Post Sale Surveillance or Post Market Surveillance.

The BARD database has some quirks and shortcomings, but it is the best tool available to identify boat accidents by manufacturer this side of insurance records which are not publicly available.

We now provide a number of BARD training videos and support materials to assist boat builders using BARD as part of their post sale safety monitoring program. This page features a large chart showing how BARD can fit into a broader program to post sale monitor accidents involving vessels built by a specific boat builder. Read More →

Our 501st post

Propeller Safety - PGIC Facebook icon

PropellerSafety

Thought we would take a moment to recognize this is our 501st post since we converted our site to a blog format back on 20 June 2011. Number 500 was published yesterday. Today is 11 July 2020. Over that same time we have had well over half a million visits.

While 500 posts is a real marker, we note our site also boasts an additional 91 Pages, each one another separate post by itself. The Pages can primarily be reached by the upper top menu bar. They are generally topics that remain current, while at least some of the posts may be more fleeting in interest level.

500 posts is a significant milestone. If you add this post, plus the 500 posts, plus the 91 Pages, that makes a total of 592 articles on this site. We hope our viewers find at least some of our propeller safety coverage helpful.

Thinking back over the years, we would be remiss if we did not mention the hundreds of people all over the world who helped us along the way by providing information and encouragement. While we don’t have time or space to thank them all, I especially thank my wife who has assisted in many ways. Plus a special thanks to Marion Irving deCruz formerly at Stop Propeller Injuries Now (SPIN) now looking over us and many others from above.

We look forward to continue publishing articles related to boat propeller safety.

We welcome your comments below.
