Need motor mount for OS 40 SR Marine

       Remove this ad - become a site supporter!
I'm installing this motor in a rigger, and need to find a motor mount that fits this motor. I am new to rc boats, so I am not too familiar with the types and manufacturers of mounts. Can anyone recommend a good brand, or does anyone have one that you're willing to sell? I am pretty sure that the motor is called a 40 SR, it's definitely a 40, it looks like a 40 fsr, but has a rear carb with rotary valve and a liquid cooled exhaust port. An old engine, but I don't think it was ever ran.

Those mounts would work for you yet you may need to remove one of the aluminum rails and bolt threw the rigger tub to keep the spacing as this mount was made for 5 in rails by the looks of them.

Another way is wooden blocks glued to the inside of the tub and custom aluminum mounting plates made that bolt down onto the wooden blocks.
