jdoug iI did some work late into the night last night and i lowered the stuffing tube,luckily for me (i hope because i epoxyed it in)i have it at 1/2 inch from the keel.I took a straight edge and put it along the bottom and 2/3 of one blade is below the keel.I'm not sure what kind of prop this blue one is though but it is about the same dia as a 540 motor so i think it is a 35mm,i will get the #'s from it.

I also made and installed a motor mount.It will allow me to pivot the motor on the centerline of the boat if i need to.

I also made a rudder arm to connect the linkage to and the servo mount.
The rudder has been lined up with the drive dog.I have built in about 1/4'' adj. so i can move it away from the transom or bring it closer if needed.
So any sugestions are welcomed,thanks a lot for helpping me with this first build.
