So my honda 9.9 doesn't have a steer tube and I'm sick of dealing with the powertran add-on tube because it is just in the way of tilt and whatnot. Anyway, the actual transom mount has holes big enough for a steer tube it just came with spacers put in. However, the actual piece that is between the transom mount and attached to the motor(I think it is called the swivel mount/shaft) only has about a 3/8" hole for a steel bar. Has anyone ever drilled one out to add a tilt tube? Anyone see any problem with doing so? It has plenty of extra space around the 3/8 hole to bore it out.
