will a flex coupler work for a solid shaft?
 

Hello, I recently built a boat. I plan to put an o.s 18 on it and I was looking at some parts off the net and all I could find for a coupler was a threaded flex coupler. will that work for a solid shaft? or do I have to find a different coupler. if so where could i find one.


Thank you.

For a solid shaft, you're better off using a universal joint type of setup. That will help with any minor misalignment between the engine and shaft.
I prefer the flex cable setup myself as that's what I'm used to but have had some boats (RTF type) that have used them. It's a cheap and easy way to build a mass-produced boat.

well do you think it would be smart to change from a solid shaft to a flex cable? I think it would make the engine installitation much easier.

Not only does it make things easier to set up but you'll have more adjustability if you have to make changes in prop height and angle for best handling. Setting up a flex cable isn't that difficult but I'm used to it.
