Well, we have learned allot about steering in trying to get this all connected. With the repairs on the boat to a point where we can install the outboard, we started to design the steering. I was in a hurry to get this on the water for vacation, so I didn't take pictures. I'll try to describe what went into the design.
The biggest issue in using a steering ram type system on an old outboard, is that the ram travels 8 inches, total and it takes 12 inches of movement, at the front of the outboard to turn it stop to stop. So how do you get full steering motion with this setup?
Well, you either use a lever to multiply the movement, see the next photos, or you move the attachment point of the steering ram back closer to the outboard's pivot point where less travel will accomplish the same thing.
After a number of prototype's this is the 'interum' steering setup. The steering tube is mounted in 3/4 inch plywood blocks that have been drilled to accept the steering tube. The blocks are bolted to the angle iron that is clamped under the outboard. This provides a solid attachment for the tube. In this setup there were several things to work around. 1. make sure you can tilt the motor up and not hit the mounts, that is why one of the blocks has the corner sanded off. 2. keep the ram and steering rod from hitting the fiberglass in the upper left of the photo.
