How’s this linkage for clean and simple?

The servo is mounted to the engine, so it will move with the motor.

Chris, scratch built or did you buy it online ?

 

[ChrisHerzog]

It’s all me. Just trying to build a better mouse trap!

 

[Ray Sametz]

Any concerns with the constant vibration?

 

[ChrisHerzog]

If that becomes an issue, I have a few ideas on how to address it. However, you have to start somewhere and the only way to find out is to go run it and make laps!!

Is servo proof seal ? if carb stuck somtime flood over gas drop on the face servo. cause fire

Its works Chris, I've been doing this on my boats and going on the 3rd season with it. I'll get a pic when I get back from traveling. End point adjustment is more critical as there is no slop in the connection to buffer it. I also use the servo rubber grommets for mounting.

Are you asking if the servo is water proof? If so yes.

That’s good to hear, would love to see pics when you can!

Ok servo build digital or brushless?

Not sure. I think digital.

 

[ChrisHerzog]

The first test went well!

Here are some pictures of the throttle servo mount.

I wasn't that concerned with the vibration as I was with the heat next to the engine . So far OK.

Doug, that looks great! I’m glad to hear that you haven’t had any problems with it.

Doesnt get any more "direct" than that....
I guess a mini servo would work as well...being there is almost no real torque needed to operate the throttle arm...

 

[ChrisHerzog]

View attachment IMG_7684.movI have at least 5 or so tanks through it so far and the servo is still working!

Arrow shark have mounted servos to their 30 and 60 motors. I was curious how they might hold up. Good to see - linkages are pretty complex on some boats. X30-Advance Version_X-30 Marine_Gas Engines_Arrow Shark RC Marine
