Several forum members have been suggesting possible solutions. We have assembled a large collection of approaches many which have already been patented by the boating industry in the past but are not...

The warning discussed above and copied below did not come from the marine drive manufacturers.
I created it as an example to encourage them to create their own.

Engine OEM's are not likely to address jack plate issues.

Engine OEMs are also not likely to add a highly visible strap to catch their outboard if it breaks off and tries to flip into the boat. ...

Thanks for mentioning our site.

I would note for those who still do not believe these accidents happen, we have an extensive list of large outboard motors flipping into boats at...

Several folks here have identified different ways a large outboard motor could break off and potentially enter a bass boat. A couple years ago we identified 9 ways a large outboard motor or...

We maintain a separate list of large outboards flipping into boats in recent years at:

I failed to supply a link to the all outboards list, that link is below:

We maintain two lists of them, one is for outboards of 150 HP and above, one is for all outboards. The all outboards list currently has about 90 accidents on it with the earliest events being in 1952...

Depends on the manufacturer, that particular model and year, if the jack plate holds or not, how fixed/solid the object is you strike (stump vs a small floating stick), what angle you hit it at,...

We maintain a list of large outboards breaking off and flipping into boats. The list is currently being updated.
If you know of one not one there, please contact us....

You are certainly entitled to your opinion.

I propose the colored areas represent an overview of the different ways a log strike system can respond, and how it can fail.
AND that the information...

I had trouble getting this text attached to the chart image above, so attaching via separate message.

There are two basic modes (ways) in which a large outboard motor can enter a bass boat that...

Most (if not all) major manufacturers of large outboard motor do some sort of impact testing of new designs. In the early days they were "on water" tests in which they drove boats over a "standard"...

We list large outboard motor flipped into the boat accidents at:

About 1978 I was living right next to a large college campus, driving about 25 miles to work, and being at work by 7am. One morning I came out of my apartment complex, walked to my pickup, and saw a...

As for us, we were thrilled to see The Leash enter the marketplace early last year. They recognized the problem, identified a solution, put their time, sweat, and money in bringing it to market. We...

Seems like there is some confusion about the various modes in which an outboard can enter a boat and which of those modes something like The Leash could prevent. We created a chart showing the...

The item labeled "Swivel plate" in my 4 February 2016 Leash installation sketch should have been labeled "Swivel bracket". I started life as a hydraulic engineer and still often write swivel plate,...

Yes, that is the earliest instance of a flipped in fatality during a bass tournament we have discovered. A 28 June 1987 article in the Daily Oklahoman on bass tournament safety includes this...

You are welcome. This is not new stuff. We just brought together a bunch of materials that have been around a long time, like this text from a 1972 U.S. Coast Guard Boating Safety Tips article on...

We cover that approach beginning of page 68 of our list of approaches linked to earlier. Various versions of this idea have been patented several times including by some of the major players. The...

The list of accidents is far from complete. 2008 is the first year the Coast Guard allowed access to what they call redacted narratives (verbal descriptions of the accidents less any private...

I have been studying "outboard flipped in" accidents for several years, and especially bass boat outboard flipped in accidents. In recent years the bass boat portion of them mostly result from swivel...
