Making a parenthesis, but knowing us better, I want to show you, what I've built ... inspired me from the web, but also with the help of people in Italy.
I was hard, but I've worked with passion, and I have led the project up to the end of work. I hope .... with your help, this time, to go and this project up to the end of work.
On that site, I wrote under the name of user 'ginghis'

And this is a clip with final product !

It is true that here, in Romania, the rate of use of these type of engines(mud-motor) is 0. I'd like to think that I am first of such engines....may be.
I typically use an engine Honda BF, 15 hp, 4t, but I have had situations, where in the Danube Delta, we couldn't pass over some obstacles with my engine. For this reason, seeing how many advantages provides this type of engine, I decided to start construction of such a motor.

Today we've worked least mud ...
For handling motor left-right, I'd have two options:
-metal-to-metal, with a fin to lubricate parts in contact.
-or else, with a thrust bearing.
I haven't decided yet, but I feel inclined to bearing.

You shouldn't need a bearing. Metal to metal would be fine. If you want it to be really smooth add an oilite bushing. (Like this )


Here is a pic of a homebuilt mounting bracket for reference.

that is a very small amount of adjustment in that picture. I doubt it would make much difference.

I don't know the role of this blockage ! If someone can tell me!
Thank you!

It locks the mount straight when the motor is rotated 180 degrees into the boat while pulling the boat on the trailer.

OK ! I understand !
Thank you, sir!

Good evening ! After I've documented, from the first support I gave up, and I decided to make another. The support, momentat is painted with a primer auto, but I don't want at the end of the project, to dye camouflage .

In the meantime, I also bought a universal coupler !

Your transom mount looks great!
Will you weld a piece of flat plate across the top for the engine to mount to?

Thank you!
I don't think so, v-sheep do that after, I finished queue engine, otherwise I don't think that it can balance .

Looking good!
Also your new universal joint should work much better than the first one you showed us.

Today we've worked something ... and bearing boxes are working on turner .

Looking good buddy, where are you from?

Today, arrived parts !

Where did you order the bearing assembly from?

I've ordered from a friend... works at a factory ...

It looks like it will work great.

I hope !
Thank's !

Thats a good looking bearing set up

I think heavy for the bearing assembly is good. If it fits the shaft, it will work well. As long as it doesn't weigh 40kg

Hows the boat your putting it on going to like that weight on the transom?

For moment, I don't know...but I like put on a "jon-boat" !
I hope, building a "jon-boat"...and I think is the best for my long-tail.

Recently, I bought a inductive tachometer ... I wrapped 4 turns on the spark plug, and we filmed a few values of engine speed.

To get the max RPM's. The more RPM's the faster it will turn the prop.(Go faster)

I understand ! ... but this will not affect engine ?
