I just bought a 1997 15hp Evinrude. I purchased a Shop Manual
thinking that that might help me figure out a couple of the features I
don't understand but it doesn't.

Like what is the little knob on the end of the tiller handle for? I t
also look like you can lock the engine in place to keep it from moving
from side to side when towing. Is that right?

I would like to have an owners manual but was unable to find a source
on the net. Any suggestions.
