kick out bracket

[speeder]

help needed in understanding functions of "kick out "bracket
thank you

[sam]

Probably talking about a thrust bracket

Its for more precise setting of the tilt angle ... also accepts thrust from the motor lower than the tilt pin, giving a little more support

"Dog bones" give the same greater tilt precision, but do not change the support point

"Dog bones" give the same...

So, what's a "Dog Bone"?

[seanp3]

I think this is what Sam is talking about. Pictures are from Brown Tool Machine

Ahhh- So a "Dog Bone" is slanglish for Thrust Bracket........
I took it to mean they were two different things, a Thrust Bracket, and this other thing called a "Dog Bone".

Thanks

Kick out

Dog bones can be differant size pipe cut to go between the clamp bracket , you slide the tilt pin though the pipe,this will change the amount of kick out an make it more precise . Keller once made a flip bracket that did about the same thing. you can use differant size pipe one inside the other to get the amount of change you want.

Portage Bay sells the Keller kick-out.

Dog Bone is Thrust Bracket?

I'm with Danny, who beat me to the post.

Don't think so...

There used to be, in common use, an adjustable shim, that went on the tilt pin of the old Mercs. There were big ones for C-D's, (I still have some), made by Keller. I think they made small ones, too. They were a tubular spreader, with a triangular aluminum pieces at each end. The tube was not centered on the triangles, so as you rotate it, so the swivel bracket came down to rest on one side or another of the triangles, the shimmed out distance changed.

So, you slipped this in between the clamps, inserted the pin, and then you had three different trim positions, 'between' pin holes. On my D boat of the day, 2nd pin hole was in too far, 3rd pin hole was out too far...

I never heard that called a Dog Bone, but it fits. We just called it a Keller kickout, although I have seen other makes.

Earlier, I used pieces of common pipe, cut to length, one piece slipped inside another for the same effect...

The thrust bracket was a big improvement, as it gave finer increments of adjustment and supported the lower unit lower down, taking some load directly to the transom. On the Mercs, the lower swivel boss was made to order...

Really clever guys went a step further and made the swivel bracket mounting plate fit precisely between the motor clamps, 3/8" thick, so it had the added benefit of locating and holding the clamp bracket captive. That minimizes that tendancy of the clamps to wrench loose off the transom in a hard turn.
Ever notice the motor always comes up on the same side? It twists. With this setup, the motor must be slid straight up, even with clamps loosened, to remove it.

I also should stress that even with a thrust bracket, you should run a tilt pin, set in the closest hole. That way, if the bracket fails, the pin catches it, and doesn't let the motor tilt all the way in...

Had a nasty DSH crash with another boat whose bracket failed. His motor came in violently, hit the broken stump of the bracket, and wrenched the motor up. That, with the sudden trim in, hooked his boat right into my path. His boat was totaled. Could have been serious injury as I bulldozed both cockpit sides right off. Fortunately he was already thrown out...

A tilt pin in place would have prevented or minimized this... Belt and suspenders.

Tilt pin

Jerry, this is good info. for racers today, I never ran any boat with out the tilt pin in place like you said, an I told other people to do the same. Wonder how many racers today run with out the tilt pin installed.

Hmmm- Guilty. I'll work on that.

Thanks for the tip.

Thrust Bracket

Ummm, Not wanting to confuse anyone, I should have said "made the thrust bracket mounting plate fit precisely between the clamps, 3/8" thick", instead of swivel bracket... Yah, its under the swivel bracket, between the clamps, but I should have stated it more clearly... Its the base plate for the thrust bracket to attach to the transom. By making it thick enough, big enough to fit precisely between the insides of the clamps and reaching up almost touching the clamp spreader assy., it does double duty.

On mine, you can see a burnish mark on the edge where the clamp bracket tried to twist and the mounting plate held it! Almost as effective as bolting the clamps down, yet it allows you to add a shim stick or two if needed.

Thrust Bracket

Here is one example of how a thrust bracket is used. I have seen many different variations but they all achieve the same goal. To fine tune the engines tilt angle in relationship to the boats running surface. Some use fine thread some use course thread. It's a matter of personal choice. Hope this helps answer your question.

1/2 holer

That's what we called it. Never heard it called a dog bone, but this one resembles a knawed up one

Evolution.

What's a tilt pin? What's a shim stick?

Well done guys!
