I have a new Prather 7.5 NIP> It is $30 plus shipping. I assume you live in Sweden?

The Prather mount is that adjustable up/down?

I´ve seen pictures of the stumpfab mount in your topic here in the outboard forum, which is adjustable up/down, but can´t find it on the stumpf seite.

Is that the next generation? If so I can wait until it´s ready.

 

[topfuel443]

Anders. Yes, that is a prototype engine mount. I am working on getting it finished now.

Great news Gabe

Thats the one I want

 

[Jarcaines]

Gabe, are the measurements the same as the Prather/MECOA mount?

 

[topfuel443]

Which measurements are you talking about? The mouning bolt pattern is the common 1.5"x.75" pattern. (like just about every 7.5/11cc mount out there) The part that goes through the transom. The rest is all StumpFAB specific.

 

[Jarcaines]

The measurement from the transom to pivot pin.

I like your bracket BUT sharp corners will fail. If I made this bracket, I would make it wit a .060 to .090 (1/16 to 3/32) radius in each corner.
When I was doing aerospace machining, way back when, the rule was NO SQUARE CORNERS. Square corners will fail.

 

[topfuel443]

Steve, square corner motor mounts exactly like this have been around for decades, and ive never seen one fail in the referenced area. Thanks for your input, and good luck with your bracket! .

That's right there is nothing wrong with square corners in aluminum it absorbs the vibration if this was a Rockwell harden bracket made out of steel I would be concerned but like Gabe said these have been around for ever awesome mount gabe
